Isolated mitochondria are able to sustain ATP synthesis when provided with ADP, Pi, O2, and a regenerating supply of NADH or FADH2 as the sole source of electrons for oxidative phosphorylation. Predict how inhibition of Complex I will affect O2 consumption and ATP synthesis. Answer choices: Decrease Increase No change Site of inhibition Sole source of electrons Oxygen consumption ATP synthesis Complex I NADH [BLANK-1] [BLANK-2] Complex I FADH2 [BLANK-3] [BLANK-4]

Given that all phosphotransferases have similar catalytic mechanisms, consider the half-reactions for the uncatalyzed transfer of inorganic phosphate from 1,3-BPG to ADP. One half-reaction produces water and the other consumes water. Observe that the phosphoglycerate kinase (PGK)-catalyzed phosphoryl transfer from 1,3-BPG to ADP does not include water. Select the best explanation for why the catalyzed reaction does not include water. uncatalyzed half-reaction 1 1,3-BPG + H2O → 3BPG + Pi uncatalyzed half-reaction 2 ADP + Pi → ATP + H2O PGK-catalyzed coupled reaction 1,3-BPG + ADP → 3PG + ATP
