A) 40%
B) 60%
C) 90%
D) 100%
Correct Answer: A
Solution :
In respiration process, total 36 ATP are produced. Each ATP molecule contains 7.6 kcal energy. Therefore total energy released in respiration is 36 times 7.6 = 273.6 kcal. But complete oxidation of glucose produces 686 kcal energy, therefore respiratory efficiency = \[=\frac{273.6}{686}\times \text{ }100\approx 40%\]You need to login to perform this action.
