Electrons can be stripped from NADH via the electron transport chain in respiration C. Pyruvate is oxidized during fermentation D. a and b E. b and c - Answer -D. a and b ATP is used as an "energy currency of the cell" because: A. The diphosphate bond is unusually stable, for a covalent bond B. Hydrolysis of the diphosphate bond has a high positive ∆G C. Hydrolysis of the diphosphate bond has a high negative ∆G D. ATP is a building block of DNA E. Both a and d - Answer -C. Hydrolysis of the diphosphate bond has a high negative ∆G NADH can be used for biosynthetic reactions, or it can be "cashed in" for ATP.
