To determine how many O2 molecules are required for two glucose molecules to undergo cellular respiration, we need to use the equation for cellular respiration. The equation is:

C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP

From this equation, we can see that 6 O2 molecules are required for one glucose molecule to undergo cellular respiration. Therefore, for two glucose molecules, the number of O2 molecules required would be:

2 glucose molecules × 6 O2 molecules per glucose molecule = 12 O2 molecules

So, the correct answer is 12.

The correct answer is 12. To understand why, we need to examine the chemical equation for cellular respiration, which is:

C6H12O6 (glucose) + 6 O2 (oxygen) → 6 CO2 (carbon dioxide) + 6 H2O (water) + energy (ATP)

From the equation, we can see that for each glucose molecule, 6 molecules of oxygen are required. Since there are two glucose molecules mentioned in the question, we need to multiply 6 by 2 to get the total number of oxygen molecules required. This gives us:

6 oxygen molecules/glucose molecule * 2 glucose molecules = 12 oxygen molecules

Therefore, the correct answer is 12.
