A: Insulin
Answer: A: Insulin 
Explanation: (Insulin): Ref: 548-RS 7'h, 309-LPInsulin increases utilization of glucose for providing energy which takes place in muscle, liver and many other tissues. Insulin enhances glycolysis t because it induces the synthesis of key enzyme phosphofrnctokinase and also "pyruvate kinase" (511-RS)Biological effect of Insulin* | Glucose uptake* | Gluconeogenesis* | Glycogen synthesis* | Glycogenolysis* | Protein synthesis* | Lipolysis* | Fat synthesis* Altered gene expression
