a. 66
b. 33
c. 1212
d. 18
d. 18
To determine the number of CO2 molecules produced when three glucose molecules undergo cellular respiration, we need to know the balanced chemical equation for cellular respiration.
The balanced equation for cellular respiration is:
C6H12O6 + 6O2 -> 6CO2 + 6H2O
From the equation, we can see that for every glucose molecule (C6H12O6), 6 CO2 molecules (6CO2) are produced.
Therefore, when three glucose molecules undergo cellular respiration, the number of CO2 molecules produced will be 3 times the number produced from one glucose molecule, which is:
3 * 6 CO2 = 18 CO2
So, the correct answer is d. 18.
To determine how many CO2 molecules are produced when three glucose molecules undergo cellular respiration, we need to understand the process of cellular respiration and the chemical equation involved.
Cellular respiration is the process by which cells convert glucose and oxygen into carbon dioxide, water, and energy in the form of ATP. The chemical equation for cellular respiration is:
C6H12O6 (glucose) + 6O2 (oxygen) → 6CO2 (carbon dioxide) + 6H2O (water) + ATP
From the equation, we can see that for each glucose molecule, 6 carbon dioxide molecules are produced. Therefore, if three glucose molecules undergo cellular respiration, we can calculate the number of CO2 molecules produced.
3 glucose molecules x 6 CO2 molecules = 18 CO2 molecules
Therefore, the correct answer is 18 CO2 molecules (option d).
