Adrenaline acts on which enzyme in glycogenolysis ?

Correct answer: C. Phosphorylase

  • A. Glucokinase
  • B. Hexokinase
  • C. Phosphorylase
  • D. Glucose diphosphatase

Explanation

Adrenaline stimulates glycogen phosphorylase through the cAMP-dependent phosphorylation cascade, causing glycogen breakdown. Glucokinase and hexokinase instead trap glucose for metabolism and are not glycogenolytic enzymes.
