This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: Four Formulas, Subject name: Biochemistry
Which of the following activate Kinase of glycolysis: 
Select and explain. 
A. ATP, B. cAMP, C. Insulin, D. Glucagon
C: Insulin
Answer: C: Insulin 
Explanation: Usually anabolic pathways are activated by Insulin. But Insulin also activates glycolysis (Catabolic pathway) as an exception. It activates:- Glucokinase, PFK-1, and Pyruvate Kinase enzymes of glycolysis. Insulin activates all anabolic pathways enzymes: HMP Glycogenesis FA synthesis Cholesterol synthesis TG synthesis Lipoprotein Lipase enzyme But Insulin also activates two catabolic pathway enzymes, i.e. Glycolysis & Link reaction.
