Humans oxidize glucose in the presence of oxygen. For each mole of glucose oxidized, about 688 kcal of energy is release. This is true whether the mole of glucose is oxidized in human cells or burned in the air. A calorie is the amount of energy required to raise the temperature of 1g of water by 1°C; 686 kcal or 686,000 calories. The average human requires about 2000 kcal of energy per day, which is equivalent to about 3 mol of glucose per day. 1)Given this, how much heat could theoretically be produced by a person eating 2000 kcal per day? 2)why doesn't this heat production cause humans to spontaneously combust?
