Unformatted text preview: glucose implies that glycerol enters glycolysis at a later step. (Glycerol, is in fact converted to DHAP, but you do not need to know that to answer the question). 3. Explain why glycolysis can occur under aerobic or anaerobic conditions. There is no step in glycolysis that uses O 2 as an electron acceptor. Glycolysis does, however, generate 2 molecules of NADH per molecule of glucose. In the absence of a functioning electron transport chain, NAD+ pools are regenerated during fermentation. 4. In the glycolytic pathway, be able to identify: Steps where the input of ATP is required Steps where ATP is synthesized by substrate-level phosphorylation Step where NAD+ is reduced to NADH How NADH is oxidized back to NAD+ in muscle, in some yeast, and under aerobic conditions Irreversible reactions (under normal cellular conditions) Regulated enzymes...
