Which factor directly results in the activation of glycogen synthase?
A) binding of glucose-6-phosphate
B) dephosphorylation of multiple residues by phosphoprotein phosphorylase-1 (PP1)
C) phosphorylation of specific residues by casein kinase II (CKII)
D) phosphorylation of specific residues by glycogen synthase kinase-3 (GSK-3)
E) the presence of insulin

Question

Quizplus · Accepted Answer

Glycogen synthase is regulated by phosphorylation and dephosphorylation. When multiple residues are dephosphorylated by phosphoprotein phosphorylase-1 (PP1), glycogen synthase is activated.
