Answer #1

GLYCOGEN METABOLISM IN LIVER:-
-glycogen metabolism in the liver mainly controlled by the concentration of phorphorylase alpha.
-The formation of phosphorylase alpha is stimulated by cAMP and by glycogen.
-The inactivation of glycogen synthetase is stimulated by cAMP, an elevated concentration of which puts a double lock on glycogen synthetase by activating phosphorylase alpha.

FUNCTIONS OF GLYCOGEN IN LIVER AND SKELETAL MUSCLE:-
- Glycogen functions in muscles as for energy source.
- In liver it is long-term energy reserves, in the form of triglyceride.

please answer 1-6 :) 1. Glycogen metabolism is regulated, up to a point, by a cyclic AMP cascade. At what point do glycogen synthesis pathways diverge from glycogen degradation pathways? a. Protein kinase A leads to the activation of glycogen degradation, and also to the inhibition of glycogen synthase by conversion from b to a. b. Phosphorylase kinase converts phosphorylase b to phosphorylase a and glycogen synthase a to glycogen synthase b. c. Protein kinase A leads to the activation...

Glucose-6-phosphate is the substrate for glucose-6-phosphatase, an enzyme found in the liver but not in the muscles or brain. (a) Why is the selective expression of this enzyme (liver vs muscle and brain) important to glucose metabolism in animals? (b) Muscle glycogen phosphorylase is inhibited by high levels of glucose-6-phosphate. Briefly explain the rationale for this inhibition.

Considering the role of Lactate Dehydrogenase in metabolism, thoroughly explain: a. Why a deficiency in the muscle form of lactate dehydrogenase makes it difficult for an individual with this condition to quickly run up three flights of stairs, but does not cause lactic acidosis. b. Why a deficiency in the liver form of lactate dehydrogenase leads to hypoglycemia and lactic acidosis. Are there conditions where this would be more of an issue?
