Transcribed Image Text:b) Percentage of the person's body weight that this represents.
A 70 kg (154 lb) adult requires a calorie intake of 2,000 kcal (8,360 kJ) of food per day (24 h). The food is metabolized and the free energy is used to synthesize ATP for useful work. [FYI: Each calorie ("Calorie") listed on food labels corresponds to 1.0 kcal in biochemical terms; the formula weight of ATP is 505 g/mol; and each mole of ATP is equivalent to 30.5 kJ]. Assuming that the efficiency of converting food energy into ATP is 50%, calculate the following: a) Weight of ATP used by this human adult in 24 h.
