Glycogen metabolism is influenced by
A) phosphorylase kinase
B) phosphoprotein phosphatase
C) epinephrine
D) all of these

Question

Quizplus · Accepted Answer

Glycogen metabolism is regulated by several enzymes and hormones. Phosphorylase kinase activates glycogen phosphorylase, which breaks down glycogen into glucose-1-phosphate. Phosphoprotein phosphatase deactivates glycogen phosphorylase, slowing down glycogen breakdown. Epinephrine, a hormone, stimulates glycogen breakdown by activating phosphorylase kinase through a signaling cascade. Therefore, all of these factors influence glycogen metabolism.
