Which of the following effectors is required for glycogen synthase activity when the enzyme is phosphorylated?

Question

Quizplus · Accepted Answer

Glycogen synthase activity when the enzyme is phosphorylated requires glucose-6-phosphate as an effector. This is because glycogen synthase is a key enzyme in glycogen synthesis, and its activity is controlled mainly by reversible phosphorylation. When glycogen synthase is phosphorylated, its activity decreases, and glucose-6-phosphate serves as an allosteric activator to promote its activity. The other answer choices are not required effectors for glycogen synthase activity when the enzyme is phosphorylated.
