To determine the number of O2 molecules required for two glucose molecules to undergo cellular respiration, we need to follow the balanced equation for cellular respiration.
The equation for cellular respiration is:
C6H12O6 + 6O2 -> 6CO2 + 6H2O + Energy (ATP)
From the equation, we can see that for each glucose molecule (C6H12O6), 6 oxygen (O2) molecules are required.
Therefore, for two glucose molecules, the number of O2 molecules required would be:
2 glucose molecules x 6 O2 molecules/gluose molecule = 12 O2 molecules.
So the correct answer is 12.
To answer this question, we need to understand the process of cellular respiration and the stoichiometry of glucose metabolism.
Cellular respiration is the process by which cells convert glucose and oxygen into carbon dioxide, water, and energy in the form of ATP. The balanced equation for cellular respiration in aerobic conditions is:
C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP
From this equation, we can see that for each glucose molecule (C6H12O6), six oxygen molecules (O2) are required. This means that the answer to the question is 6.
Therefore, the correct answer is:
• 6
