Question

Smaller mammals use proportionately more energy than larger mammals; that is, it takes more energy per gram to power a mouse than a human. A typical mouse has a mass of 20 g and, at rest, needs to consume 3.0 Cal each day for basic body processes.

(A) If a 68 kg human used the same energy per kg of body mass as a mouse, how much energy would be needed each day? (E=?)

(B) What resting power does this correspond to? (P=?)

(C) How much greater is this than the resting power noted in the chapter? (P=?)

Explanation / Answer

= 150 cal/day

For human of 68 kg = 150*68 = 10200 Cal/day

2. Resting power or BMR = (10200*4186)/(24*3600) = 494.18 W

3.resting power noted in the chapter = must be 2000 cal/day for common

10200/2000 = 5.1 times more than resting power

Or if book mention in W (i.e. 1000W then it will be 1000 - 494.18 = 505.82 W)
