Main source of energy derived from: (A) Fat, (B) Glycogen, (C) Lactate, (D) Ketone
Answer is B. Glycogen is the reserve carbohydrate in animals. It is stored in liver and muscles.The phosphorylated enzyme is less sensitive to allosteric inhibitors. Thus even if cellular ATP and glucose-6-phosphate are high, Phosphorylase will be active. The glucose-1-phosphate produced from glycogen in the liver may be conveed to free glucose for release to the blood.
