How many oxygen molecules (O₂)are required each time a molecule of glucose (C₆H₁₂O₆)is completely oxidized to carbon dioxide and water via aerobic respiration,?
A) 1
B) 3

Question

Quizplus · Accepted Answer

The balanced equation for the oxidation of glucose to carbon dioxide and water is:

C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O

This means that for every molecule of glucose that is oxidized, 6 molecules of oxygen are required. Therefore, the correct answer is C) 6 oxygen molecules.
