Document Summary
Chapter 9 - cellular respiration and fermentation: the three stages of cellular respiration are glycolysis in the cytosol, pyruvate processing in the mitochondria, and the citric acid. In glycolysis, glucose goes in, turns into glucose-6-phosphate, then fructose-6-phosphate, fructose-1,6-biphosphate, dihydroxyacetone phosphate splits off, glyceraldehyde-3-phosphate, 1,3-bisphosphoglycerate, 3-phsophoglycerate, 2- phosphoglycerate, phosphoenolpyruvate, and ends as pyruvate: atp is used to power enzymes one and two in glycolysis. There is a gross total of 4 atp created in glycolysis, but a net total of: nad+ is reduced in step six of glycolysis after enzyme 6. Inside the mitochondria, pyruvate reacts with a compound called coenzyme a. coa acts as a coenzyme by accepting and then transferring an acetyl group to a substrate. Pyruvate reacts with coa, through series of steps, to produce acetyl coa: the citric acid cycle is called a cycle because it uses it products to continue with the help of some outside acetyl coa.
