Question

for each molecule of glucose, how many carbon dioxide molecules are produced?
o 2
o 4
o 6
o 8

Explanation:

Step1: Recall glucose oxidation equation

The chemical formula of glucose is $C_6H_{12}O_6$. During cellular respiration (complete oxidation of glucose), the balanced chemical equation is $C_6H_{12}O_6 + 6O_2
ightarrow6CO_2+6H_2O$.

Step2: Determine CO2 produced

From the equation, for each molecule of glucose ($C_6H_{12}O_6$) oxidized, 6 molecules of carbon - dioxide ($CO_2$) are produced.

Answer:

C. 6
