To determine the number of CO2 molecules produced when three glucose molecules undergo cellular respiration, we need to start by understanding the chemical equation for cellular respiration of glucose. The balanced equation is:
C6H12O6 + 6 O2 -> 6 CO2 + 6 H2O
This equation tells us that for every glucose molecule (C6H12O6) consumed, six molecules of CO2 (carbon dioxide) are produced.
Therefore, when three glucose molecules undergo cellular respiration, the equation would be multiplied by a factor of 3:
3 C6H12O6 + 6 O2 -> 18 CO2 + 18 H2O
So, the correct answer is 18 CO2 molecules produced.
To determine the number of CO2 molecules produced when three glucose molecules undergo cellular respiration, we need to know the chemical equation for cellular respiration.
The balanced equation for cellular respiration is:
C6H12O6 + 6O2 → 6CO2 + 6H2O + energy
From the equation, we can see that for every glucose molecule (C6H12O6) consumed, 6 molecules of CO2 are produced.
Since three glucose molecules are undergoing cellular respiration, we can simply multiply the number of CO2 molecules produced per glucose molecule by the number of glucose molecules:
6 CO2 molecules/glucose molecule * 3 glucose molecules = 18 CO2 molecules
Therefore, when three glucose molecules undergo cellular respiration, 18 CO2 molecules are produced.
So the correct answer is 18.
