The number of O2 molecules required for two glucose molecules to undergo cellular respiration would be 12.
First, let us look at the balanced equation of respiration:
[tex]C_6H_1_2O_6 + 6O_2 ---> 6CO_2 + 6H_2O[/tex]
From the equation, for every 1 mole of glucose molecule, 6 moles of O2 is required for complete reaction.
Thus, 2 glucose molecules will require 6 x 2 = 12 moles of O2.
