CELLULAR METABOLISM : A FEW NUMBERS

🔹Each molecule of ATP can produce 7.6 kcal of energy

🔹Aerobic metabolism of 1 mol of glucose generates 38 mol of ATP.

🔹A total of 288 kcal is produced per 1 mol of glucose. Ideally it can liberate 686 kcal; so this process is only 42% efficient.

🔹 Under aerobic conditions, during glycolysis,  2 ATPs are used but 4 ATPs and 2 NADH are generated. Under anaerobic conditions, NADH is not produced. 

🔹 A total of 325 g of glycogen is stored within skeletal muscle (75%) and the liver (25%).  Only 3% of the total energy available from glucose is utilised in the process of glycogenolysis; So storage of glucose as glycogen is highly efficient 

🔹 The HMP shunt produces Carbon dioxide, ribose-5-phosphate and NADPH but '0' ATP.
