production. The second step is pyruvate oxidation. Each pyruvate from glucose goes to the inner most spot in matrix of the mitochondria. In the mitochondria pyruvate is converted into a two-carbon molecule bound to coenzyme. Then carbon dioxide is released and NADH is produced. A coenzyme is a nonprotein compound that is necessary for the functioning of an enzyme. The third step is citric acid cycle or the Krebs cycle. The acetyl CoA made in step two comes together with a four-carbon molecule and goes

are produced. Pyruvate oxidation‚ in the mitochondrial matrix‚ is where pyruvate is oxidized to acetyl coenzyme (CoA) and CO2. NAD+ is reduced to NADH for each oxidation. Since two molecules of pyruvates are produced at the end of glycolysis‚ pyruvate oxidation operates twice for every glucose molecule. The end products of this reaction are two CO2 and two Acetyl CoA (acetate bounded to Coenzyme A). The Citric Acid Cycle is composed of eight reactions that also occur in the matrix of the mitochondria

Cellular respiration is the process by which food is broken down and converted into usable energy for the body. Essentially during this principally catabolic process‚ glucose molecules are broken down into energy known as adenosine triphosphate (ATP). Thus‚ glucose is the common energy source in cellular respiration. The process of cellular respiration begins with one glucose molecule and oxygen that yields the production of ATP as well as byproducts of water and carbon dioxide. This process is separated

6CO2 + 6H2O + energy Aerobic respiration is a stage of cellular respiration that requires oxygen. When oxygen is present the pyruvic acid molecules enter the citric acid cycle as acetyl coenzyme A. This is also how fatty acids enter the citric acid cycle. During the citric acid cycle‚ the acetyl coenzyme A molecules are converted into carbon dioxide and water. The final step of aerobic cellular respiration is the electron transport system during which ATP molecules are charged with energy. At

THE ROLE OF PROTEIN MISFOLDING AND AGGREGATION IN BSE When a protein misfolds it changes its behavior and function. If it becomes hydrophobic after once being polar. The properties and functionality of the protein are no longer useful to the organism and disaster results. PrPSc is hydrophobic‚ it avoids water inside of the cell…it attracts and attaches other proteins to misfolds and become hydrophobic …Misfolding spreads because the PrPSc act as chaperone proteins to convert PrPc TO PrPSc and

of storage pathways‚ such as lipogenesis. Insulin stimulates lipogenesis in three main ways. Malonyl-coenzyme A In fat synthesis‚ the enzyme pyruvate dehydrogenase‚ which forms acetyl-coA‚ and also acetyl CoA carboxylase which forms malonyl-coA are obvious control points. These are activated by insulin. This leads to an overall increase in the levels of malonyl-coenzyme A‚ which is the substrate required for fat synthesis. Thus‚ the flux down storage pathway is increased when there
