Answer:
d) A constitutively active mutant form of PKA in skeletal muscle cells would lead to an excess in the amount of glycogen available.
Explanation:
This occurs in the process of Glycogenolysis. The process involves breaking down of glycogen to glucose -1- phosphate and glycogen which helps in the release of glucose into the blood stream to prevent hypoglycemia(low blood sugar). The glucose-1-phosphate is later converted to glucose -6-phosphate. The latter enters the glycolytic pathway in which the reaction is catalysed by the enzyme phosphoglucomutase.
This homeostatic glucose regulation is regulated by the protein kinase(PKA)/ cAMP pathway in the skeletal muscles, the liver and the pancreas.
