  • Le Fermentation In this video we describe a few products of glycolysis and fermentation. During glycolysis, electrons are removed from a six-carbon molecule of glucose, which produces two three-carbon molecules of pyruvate. As a result of this process, high-energy molecules called NADH and ATP are formed, which provides the organism in which glycolysis takes place with a small amount of energy. The process of glycolysis is anaerobic, which means that it does not require oxygen in order to take place. Since glycolysis does not rely on the presence of oxygen, it seems reasonable to assume that the earliest life forms, which developed under anaerobic conditions, used glycolysis as a means to obtain energy. When glycolysis occurs in the yeast cell, the pyruvate which is produced undergoes fermentation. During fermentation, enzymes break down pyruvate, which reduces it to ethanol and carbon dioxide. Upon completion of fermentation, NAD is recycled in order to produce more ATP, which allows for further glycolysis reactions.

  • Glycolysis II This course is part of a series taught by Kevin Ahern at Oregon State University on General Biochemistry. For more information about online courses go to ecampus.oregonstate.edu 1. Regulation of glycolysis occurs through 3 enzymes - hexokinase, PFK, and pyruvate kinase. Hexokinase is regulated by substrate-level regulation. PFK is regulated allosterically by ATP (turns off), AMP (turns on), citrate (turns off), and F2,6BP (strongly turns on). Note that ATP and citrate will be present when cells have a lot of energy, so it is logical that they turn off the enzyme. By contrast, AMP is present when cells have little energy and it is logical that it turn on the enzyme under these conditions. F2,6BP can counteract the negative effects of ATP on the enzyme to some extent. 2. Note also that PFK is very unusual in being negatively regulated by a molecule (ATP) that is also a substrate. This is possible because the enzyme has an allosteric binding site for ATP in addition to the substrate binding site and the Km for the allosteric site is higher than the substrate binding site. 3. Pyruvate kinase is regulated both allosterically andby covalent modification (phosphorylation/dephosphorylation). Phosphorylation of the enzyme by a protein kinase turns the enzyme activity down, whereas F1,6BP acts as an allosteric activator. This activation is known as feedforward activation. 4. Feed forward activation is rare in metabolism. It is a term used to describe a metabolic product (such as F1 ...

  • Gluconeogenesis This course is part of a series taught by Kevin Ahern at Oregon State University on General Biochemistry. For more information about online courses go to ecampus.oregonstate.edu 1. Glycerol is a breakdown product of fat metabolism. Glycerol can be metabolized in glycolysis by conversion to glycerol-3-phosphate and then to DHAP, a glycolytic intermediate. 2. Gluconeogenesis accomplishes the reverse of glycolysis - synthesis of glucose from pyruvate using four different enzymes to replace three energetically unfavorable reactions in glycolysis. 3. Gluconeogenesis does not occur in all tissues of the body. The primary gluconeogenic organs of the body are the liver and part of the kidney. 4. The enzymes unique to gluconeogenesis Pyruvate Carboxylase and PEP carboxykinase (PEPCK) instead of Pyruvate Kinase of glycolysis, Fructose 1,6 Bisphosphatase (F1,6BPase) instead of Phosphofructokinase (PFK) from glycolysis, and Glucose-6-phosphatase (G6Pase) instead of Hexokinase from glycolysis. 5. F1,6BPase and G6Pase act by similar mechanisms, clipping a phosphate from their substrates and thus avoiding synthesis of ATP, which is what would be required if the glycolysis reactions were simply reversed. 6. One reaction of gluconeogenesis occurs in the mitochondrion. It is catalyzed by pyruvate carboxylase and yields the four carbon intermediate, oxaloacetate. The carboxyl group is added in forming oxaloacetate thanks to the coenzyme biotin, which carries carbon dioxide for attachment ...

  • Fermentation Products: Lactic Acid, Chocolate, and Wine Glycolsis occurs when a molecule of glucose is oxidized into pyruvate. It occurs in most organisms and is the most ancient metabolic pathway. After pyruvate is produced, two processes occur depending on whether or not there is a presence of oxygen. In anaerobic conditions, or without the presence of oxygen, fermentation takes place. During this process, pyruvate, which is a toxin, is reduced to ethanol and lactate. As a by-product, small amounts of ATP are produced along with carbon dioxide. When we exercise, our skeletal muscles ferment glucose into lactic acid. It serves as a fuel source for cardiac muscle as well as brain neurons. In this video we will discuss in detail the manufacturing of wine and chocolate. Fermentation is very important when it comes to manufacturing foods. Because of ethanol, goods like chocolate, wine, bread, cheese and tofu are able to be produced. In this video we will discuss in detail the manufacturing of wine and chocolate. The production of wine is made through fermentation of crushed grapes using an assortment of yeasts which consume the sugars found inside of the grapes and converts them into alcohol. The chocolate we love and eat would not be so tasty without the process of fermentation. Because of the intense bitter taste of the cacao(ca-cow) seed, they must be fermented to develop the flavor. Fermentation is what gives the beans their familiar chocolate taste.

  • Bread Fermentation Fermentation is an anaerobic metabolic pathway that occurs after the process of glycolysis, breaking down a glucose molecule making a pyruvate. During fermentation process, a pyruvate will further be broken down into either ethanol or lactic acid (which are both toxins). In the case of yeast fermentation, a pyruvate is broken down into ethanol. The smell of baking bread is in part due to the smell of ethanol. Fermentation can produce important nutrients or eliminate antinutrients. Depending on the type of fermentation, some products can be harmful to people's health. Food fermentation has been said to serve five main purposes: 1) Enrichment of the diet through development of a diversity of flavors, aromas, and textures in food substrates. 2) Preservation of substantial amounts of food through lactic acid, alcohol, acetic acid and alkaline fermentations. 3) Biological enrichment of food substrates with protein, essential amino acids, essential fatty acids, and vitamins. 4) Detoxification during food-fermentation processing. 5) A decrease in cooking times and fuel requirements.
  • I Dream of Aerobic Respiration Our final lab video was a presentation of aerobic respiration, Lab number 9. Aerobic respiration is a process that produces large amounts of ATP in the mitochondrion in the presence of oxygen. The process starts off with pyruvate entering the inner matrix, which is called krebs cyle. During the cycle, pyruvate circles around in the inner matrix and releases ATP and CO2. The pyruvate is changed by a series of reactions to highly reduced electrons called NADH and FADH2. The NADH and FADH2 donate their electrons to the nearby cytochrome. The cytochromes form a chain-like structure on the inner membrane and pass these newly gained electrons down the chain. Making the cytochrome excited and thus pumping protons from the inner matrix into the intermembrane space, through active transport. Chemiosmotic gradient is formed next, this begins when the intermembrane is pH 5 and the inner matrix is pH 7. The ATP synthase becomes activated and forms a channel which allows the built up the protons to pass through the channel, through passive transport, moving back into the inter matrix. When the protons exit the ATP synthase they move with a great deal of energy which phosphorylates ADP and P into ATP.
  • suffocation The aim of our video is to show the role of Oxygen in our atmosphere. Oxygen allows the creation of ATP through aerobic respiration. There are three steps in the process (Krebs Cycle, Electron Transport Chain, Formation of Chemiosmotic gradient). First, Pyruvate enters the Krebs cycle, is processed, broken down, and turned into NADH and FADH2 which are highly oxidized molecules. These molecules give off electrons which are passed down the electron transport chain onto the ultimate reciever, OXYGEN. When there is no oxygen in the system, (like when a pillow is used to suffocate someone), the electrons can't be passed on. Eventually the system backs up, the Krebs cycle stops, and Pyruvate (which is toxic) builds up in the system. At this point, ATP stops being produced in the MItochondria, and you die of Pyruvate poisoning which terminates cellular functions.

I provide it (and subsequent ones) for your information and not as a mechanism of dumping more information on you. Use them if they help you to recall the material. Otherwise, don't bother. 1. Both oxidative decarboxylation (in higher cells) and non-oxidative decarboxylation (in yeast) use an enzymatic activity called the pyryvate dehydrogenase complex to convert pyruvate from glycolysis into acetyl-Coa for the citric acid cycle. This enzyme complex is in the mitochondrion and requires that pyruvate from the cytoplasm be transported to the mitochondrion. This complex includes the following: Pyruvate decarboxylase (your book calls it "Pyruvate Dehydrogenase Component" (E1) Dihyrolipoamide transacetylase (E2) Dihyrolipoamide dehydrogenase (E3) It also uses the coenzymes, Thiamine Pyrophosphate (TPP), Lipoamide, NAD, FAD, and Coenzyme A (also called CoASH or CoA). 2. The mechanism of the reaction catalyzed by the complex is very similar to that catalyzed by the alpha-keto-glutarate dehydrogenase complex of the Citric Acid Cycle. Both involve oxidation of alpha-keto acids. 3. In aerobic higher organisms, the reaction mechanism involves binding of pyruvate by an ionized TPP, decarboxylation, transfer to the lipoamide molecules, linkage of the acetyl group to ...
  • Death by Aerobic Respiration Aerobic Respiration is the process of creating energy (ATP) in the Mitochondrion. This begins with the Krebs Cycle. Pyruvate is partially broken down by enzymes. The two products, NADH and FADH2, give up an electron that is then passed to the first Cytochrome along the electron transport chain. The electron is passed to every cytochrome and then Oxygen acts as the terminal electron receptor. During this process, Cytochromes get excited when receiving the electron and pump protons into the intermembrane space. This results in the Chemiosmotic Gradient. ATP Synthase opens up a tube allowing for the protons to rush out to the inner matrix, resulting in ADP turning into ATP. ATP is the energy used in physiological processes. If Oxygen is restricted from the body, it causes a back-up along the electron transport chain. However, Glycolysis is still occurring and creating Pyruvate. The lack of Oxygen and back-up of electrons prevents Pyruvate from being broken down and turns into a lethal substance when in high doses.
  • Cellular Respiration -- Step One: Glycolosis Glycolosis The primary objective of glycolysis is to produce pyruvate so that the proceeding process called the Link Reaction may occur. Glycolysis produces a small and very limited amount of ATP without oxygen; hence the name anaerobic reaction. Without oxygen, the Link Reaction cannot occur; if the link reaction cannot occur, the produced pyruvate is converted into other, more easily accessible substances. Humans convert pyruvate to Lactic Acid, while yeast converts the pyruvate to Ethanol. Song: BT - Rose of Jericho El Dorado High School

  • Glycolysis Do Re Mi A fun way to remember the steps in glycolysis (the breakdown of glucose into pyruvate). Let's start at the very beginning A very good place to start When you eat carbohydrates Salivary amylase will break it down, break it down Then pancreatic amylase breaks it down to maltose (and maltotriose and alpha-limit dextrins which, along with other di and trisaccharides, get broken down along by enzymes on the intestinal wall that end with ase into glucose, galactose and fructose) SGLT1 is key Transports glucose into me First, Glucose, Glucose 6-P Then it's Fructose 6-Phosphate Fructose 1,6-bis-Phosphate Glyceraldehyde-3-P 1,3-bis-Phosphoglycerate Then 3-Phoshophoglycerate Next 2-Phosphoglycerate Phosphenolpyruvate (PEP) Pyruvate Pyruvate dehydrogenase Turns pyruvate to Acetyl CoA When you know the steps to take Glucose turns to pyruvate! And now you know glycolysis Good luck! ***Note: the music is used under the fair use clause of the copyright law as it is for clearly for educational purposes and not for profit.
