Some metabolic pathways are regulated in part by changes in the rate of degradation of key enzymes.This is an example of
A) operon control.
B) transcriptional control.
C) liquid hybridization.
D) posttranslational control.
E) feedback inhibition.

Question

Quizplus · Accepted Answer

Posttranslational control refers to the regulation of protein activity after the protein has been synthesized. In this case, changes in the rate of degradation of key enzymes can affect the amount of active enzyme present, thus regulating the metabolic pathway.
