Enzyme Regulation by Negative Feedback Involves

Enzyme regulation by negative feedback involves

A) allosteric inhibition of an enzyme by a product of its metabolic pathway.
B) allosteric facilitation of an enzyme by a substrate of its metabolic pathway.
C) allosteric modification of a substrate by an enzyme of an alternate metabolic pathway.
D) occupation of the active site of an enzyme so that it catalyzes less efficiently.
E) enhancement of the active site by a negatively charged substrate.
