Regulation of Enzyme Activity Occurs

Question

Regulation of enzyme activity occurs
A) at the start of transcription.
B) at the start of translation.
C) posttranslationally.
D) at any point on the enzymatic production pathway.

Accepted Answer

Regulation of enzyme activity occurs posttranslationally, which means it occurs after the protein is synthesized. This can involve modifications such as phosphorylation or changes in conformation that affect the enzyme's activity. Regulation can also occur at any point on the enzymatic production pathway, such as through allosteric regulation or inhibition of upstream enzymes. Regulation does not occur at the start of transcription or translation, as these processes are involved in the synthesis of the protein, not its regulation.
