Select and explain. 
A. Hepatic glycogen, B. Blood glucose, C. Glycogen in adipose tissue, D. None of the above
A: Hepatic glycogen
Answer: A: Hepatic glycogen 
Explanation: Major carbohydrate store in the body is Hepatic glycogen, Hepatic glycogen maintains blood glucose concentration. No glycogen is stored in adipose tissue. In % glycogen stored in muscles> liver Body stores energy in the form of carbohydrates (glycogen) and not in form of fats because : Fats cannot be metabolized anaerobically. Mobilization of glycogen is faster than fats Fats can never be conveed to glucose Fatty acids cannot cross Blood Brain Barrier (BBB)
