Answer
$52.5\%$
Work Step by Step
Respiration produces 30 moles of ATP from 1 mole of glucose.
Comparing this number with the answer in part (a):
Efficiency of ATP production from glucose = (ATP produced / Maximum ATP possible) × 100
Efficiency of ATP production = (30 moles / 57.17 moles) × 100 ≈ 52.5%
