The heat of combusion of glycogen is about `476 kJ mol^(-1)` of carbon. Assume that average heat loss by an adult male is `150W`. If we were to assume that all the heat comes from oxidation of glycogen, how many units of glycogen `(1mol` carbon per unit) must be oxidised per day to provide for this heat loss?

Explanation

Total energy required in the day
`=(150xx24xx60xx60)/(1000)kJ" "(1" watt "=J" "sec^(-1))`
`=12960kJ`
Units of glycogen required `=(12960)/(476)=27.22` units
