Richest energy compound is
a)	Creatine phosphate	b)	Protein	c)	Carbohydrate	d)	fat

(a)

Creatine phosphate is a reservoir of high energy phosphate in muscle cells, as the energy released by its hydrolysis is greater than ATP. Fat contains more energy as compared to carbohydrate and protein. It is not directly used in respiration instead first broken down to intermediates common to glucose oxidation, ., acetul Co-A, glyceraldehydes phosphate.
