21. An allosteric regulator decreases the rate of an enzyme reaction by changing - the shape of the enzyme's active site.
- binding at the active site of the enzyme.
- changing the overall free energy of the reaction.
- acting as a coenzyme for the reaction.
- decreasing the activation energy of the reaction.
36. In the conversion of pyruvate to acetyl CoA,
- an acetyl group is transferred to Coenzyme A to produce acetyl CoA.
- only one pyruvate molecule loses one carbon atom with the release of carbon dioxide.
- the succinate dehydrogenase complex requires four coenzymes.
- electrons are transferred to NADH to produce NAD*.
