Question

Value based questions.
A camel stores fat in the hump primarily as a water source rather than as a energy source.
Carbohydrates could also be used as a water source in the same process. What advantage does fat have over carbohydrate?

Answer 1

Hint: The hydrogen part of carbohydrate molecules yields water of oxidation $(2H_2+O_2\to 2H_{2}O)$ and fats contain relatively more hydrogen than carbohydrates on a weight basis (nearly twice as much).
