A camel stores fat in the hump primarily as a water source rather than as an energy source.
(a) By what metabolic process would water be made available from fat ?
(b) Carbohydrates could also be used as a water source in the same process. What advantage does fat have over carbohydrate ?

Explanation

(a) Hint : Cell respiration (internal or tissue y respiration), fat undergoes oxidation.
(b) Hint : Only the hydrogen part on carbohydrate and fat molecules yields water on oxidation `(2H_2 + O_2 rarr 2H_2O)` and fats contain relatively more hydrogen than carbohydrates on a weight basis (nearly twice as much).
