The heat of combustion of glycogen is about 432 kJ/mol of carbon. Assume that average rate of heat loss by an adult male is 150 W. If we were to assume that all the heat comes from the oxidation of glycogen, how many units of glycogen (1 mole carbon per unit) must be oxidized per day to provide for this heat loss?
Answer:
30.00
Solution:
The daily heat loss is calculated as:
150 J/s × 86400 s/day = 1.296 × 107 J = 12960 kJ
The units of glycogen consumed per day are:
12960 kJ/(432 kJ/unit) = 30 units
Therefore, the answer is 0030.
