ATP is a Negative Allosteric Effector for Glycogen Phosporylase

Question

ATP is a negative allosteric effector for glycogen phosporylase. This is an example of
A) feedback inhibition.
B) positive cooperativity.
C) negative cooperativity.
D) competitive inhibition.

Accepted Answer

ATP acts as a negative feedback inhibitor for glycogen phosphorylase, causing a decrease in the enzyme's activity. This is an example of feedback inhibition, where the end product of a metabolic pathway inhibits an earlier step to prevent overproduction.
