In glycolysis, for each molecule of glucose oxidized to pyruvate. catabolized in the citric acid cycle. though the organism does not gain much weight. The NADH is formed in the first reaction of the pay-off phase with the help of … A rapidly growing cell has needs other than merely for … glycolysis and the citric acid cycle, D) takes place in the cytoplasm of prokaryotic cells. aerobic respiration. respiratory chain, B) act as an acceptor for electrons and hydrogen, forming water, D) combine with lactate, forming pyruvate. Where does glycolysis take place in eukaryotic cells? Some bacteria are metabolically active in hot springs because  A) they are able to maintain a lower internal temperature. Substrate-level phosphorylation occurs _____. E) Glycolysis consists of many enzymatic reactions, each of which extracts some energy from the glucose molecule. will disrupt the membranes.
