Why high levels of ATP would decrease glycogenolysis if the glycogen degradation requires ATP but in Gluconeogenesis high levels of ATP would increase the reaction?
Homework Answers
High level of ATP is a surrogate marker for high level of glucose in blood,because glucose in blood is high there is no need for glycogenolysis (which makes glusoce from glycogen),so it inhibits glycogenolysis.Also excess of glusoce has to be stored in the form of glycogen,so high levels of ATP induce it .

Arrange in proper order the events of the signal-transduction cascade for glycogen degradation in muscle. Muscle contraction begins. Phosphorolysis of glycogen yields glucose l-phosphate. Answer Bank Phosphorylase kinase is phosphorylated on its and a subunits. Intracellular CAMP levels increase, which activates protein kinase A. Epinephrine is released and binds to muscle ß-adrenergic receptors. The stimulatory G, protein dissociates and activates adenylate cyclase. Phosphorylase kinase is partly activated by binding Ca2+ Glycogen phosphorylase b is converted to glycogen phosphorylase a.

A liver cell has high NADH, high acetyl-CoAs, and high levels of pyruvate high levels of ATP, and low levels of AMP. Now suppose this liver cell needed to generate NADPH. Propose a series of pathways that the liver could accomplish this starting with pyruvate. Could the liver satisfy its needs with glycogen? Explain. 4.
