Consider the remarkable structure of the F1Fo ATP synthase shown in the following schematic drawing. Answer the following question(s) based on the structure.

-With about 7000 c-ring revolutions per minute, on average how many moles of these pumps should be working at each moment in an entire human body to make about 50 kilograms of ATP per day? The molecular weight of ATP is about 500.

Quizplus · Accepted Answer

The number of pumps is calculated as:
(50,000 g/day ÷ 500 g/mole ATP) ÷ (7000 revolution/min × 60 min/h × 24 h/day ÷ 3 ATP/revolution/pump)
= (100 mole.ATP/day) ÷ (3,360,000 ATP/pump/day)
= ~3 × 10-⁵ mole.pump
