B. Muscle glycogen                  
C. Adipose tissue                  
D. Blood glucose

Ans. C 

Adipose tissue

·         Fatty acid stored in adipose tissue in form of neutral TAG, serve as the body’s major fuel storage reserve. It is highly concentrate source of energy as it is highly reduced, largely anhydrous and yield 9 kcal/gm energy (as compared to 4 kcal/g of protein & carbohydrate).

·         Fat stores constitue 75% of energy reserve and protein stores 25%. Glycogen is the smallest resource of stored energy. Metabolic fuel stores in 70 kg man are

·         Fat: 15 kg = 135, Kcal > Protein: 6 kg = 24, 000 Kcal > Glycogen: 0.2 kg = 800 Kcal.
