Cyclic AMP … View the full answer WebApr 16, 2024 · The distinction is that hydrolysis reactions use water to cleave bigger molecules into smaller ones, but phosphorolysis reactions use phosphate instead for the same purpose. Note that the phosphate is just that - it does NOT come from ATP.

WebThe rate-limting enzyme is glycogen phosphorylase. While a hydrolase uses water to break bonds, a phosphorylase uses an inorganic phosphate. Glycogen phosphorylase is activated by glucagon in the liver, but AMP and epinephrine in the liver. It is inhibited by ATP. Glycogen phosphorylase can only break α-1,4 bonds. WebPP2A has significant phosphorylase phosphatase activity and it is active in the absence of Ca2+ and Mg 2+. Both PP2B and PP2C have very low phosphorylase phosphatase activity and they require Ca 2+ -calmodulin or Mg 2+ for activity, respectively.
