The Nutrition Facts label on most food products shows % daily values based on a food energy requirement of 8,360 kJ (2,000 kcal) at normal resting state. a) Assuming that the efficiency of converting food energy to ATP is 50%, calculate the mass of ATP (in kg) that is harvested daily by the human body from 8,360 kJ of food energy. A total of 30.5 kJ of energy is needed to synthesize one mole of ATP under standard conditions. The molar mass of ATP is 505 g/mol. b) For an average 68-kg (150 lbs.) human adult, calculate the % mass of extracted ATP (from your answer in 2a) relative to body weight.

Question
The Nutrition Facts label on most food products shows % daily values based on a food energy
requirement of 8,360 kJ (2,000 kcal) at normal resting state.
a) Assuming that the efficiency of converting food energy to ATP is 50%, calculate the mass of ATP (in
kg) that is harvested daily by the human body from 8,360 kJ of food energy. A total of 30.5 kJ of energy
is needed to synthesize one mole of ATP under standard conditions. The molar mass of ATP is 505
g/mol.
b) For an average 68-kg (150 lbs.) human adult, calculate the % mass of extracted ATP (from your
answer in 2a) relative to body weight.
