7. High levels of which molecule in the liver mitochondria promote ketogenesis rather than the citric acid cycle? (A) High glucose (B) High acetyl-CoA (C) High pyruvate (D) High malonyl-CoA (E) Low NADH and high citrate

1. Compare the two reaction coordinate diagrams below and select the answer that correctly describes their relationship. In eachcase, the single intermediate is the ES complex.Free energy, (A) Diagram (a) describes a strict "lock and key" model, whereas diagram (b) describes a transition-state complementarity model. (B) The activation energy for the catalyzed reaction is #5 in diagram (a) and is #7 in diagram (b). (C) The activation energy for the uncatalyzed reaction is given by #5 + #6 in diagram (a) and by #7 + #4 in diagram (b). (D) The contribution of binding energy is given by #5 in diagram (a) and by #7 in diagram (b). (E) The ES complex is given by #2 in diagram (a) and #3 in diagram (b).
