A) Acetyl coA is made from pyruvate in the [ Select ] ["mitochondrial matrix", "cytoplasm", "", ""] by [ Select ] ["pyruvate dehydrogenase", "succinate dehydrogenase"] complex. In this process, the acetyl group is moved between enzymes within the complex by the [ Select ] ["lipoamide", "TPP"] . The [ Select ] ["dihydrolipoyl transacetylase", "pyruvate dehydrogenase component"] is the enzyme in which acetyl coA is actually formed. The [ Select ] ["FADH2", "lipoamide"] in the dihydrolipoyl dehydrogenase donates two electrons to...

In glycolysis, one glucose molecule yields pyruvates, ATP and NADH. Depending on the system used to shuttle the electrons from NADH into mitochondria, these NADH become NADH or FADH2. Converting the pyruvate(s) into acetyl-CoA's produces 2 NADH. One pyruvate/Two pyruvates pass(es) through the citric acid cycle starting with acetyl-CoA produces GTP, FADH2, and NADH. In the electron transport chain, each FADH2 generates ATP and each NADH ATP.
