A) 1
B) 3
C) 6
D) 12
E) 30

Question

Quizplus · Accepted Answer

The complete oxidation of one molecule of glucose (C6H12O6) in aerobic respiration requires 6 molecules of oxygen (O2) to produce 6 molecules of carbon dioxide (CO2) and 6 molecules of water (H2O), according to the balanced chemical equation: C6H12O6 + 6O2 → 6CO2 + 6H2O.
