Answer 1

In cellular respiration, one glucose molecule (C6H12O6) requires 6 oxygen molecules (O2) to completely oxidize into carbon dioxide (CO2) and water (H2O). Therefore, for two glucose molecules, the number of oxygen molecules required would be:

6 O2/molecule x 2 molecules = 12 O2

So, the correct response is **12**.
