How much glucose, in grams, does the body break down per minute?

It depends on the size of the body and what it is doing. (A sleeping baby uses a lot less than a 200-pound, old-fashioned lumberjack swinging an ax all day.)

For an estimate, suppose the body's diet consists of 2000 kcal/day.
The heat of combustion of glucose is 2800 kJ/mol.
A mole of glucose weighs 180.1559 grams.

(2000 kcal/day) x (4.184 kJ/kcal) / (1440 minutes/day) / (2800 kJ/mol) x (180.1559 g/mol) =
0.374 g/min glucose...Show more
