Question

multiple choice question
which gas is produced by cellular respiration?
o hydrogen
o carbon dioxide
o nitrogen
o oxygen

Explanation:

Cellular respiration is a process where cells break down glucose to produce energy. The chemical equation for aerobic cellular respiration is \(C_6H_{12}O_6 + 6O_2
ightarrow6CO_2 + 6H_2O+\text{energy}\). From this equation, we can see that carbon dioxide (\(CO_2\)) is a by - product. Oxygen (\(O_2\)) is a reactant, nitrogen (\(N_2\)) is not directly involved in the main reaction of cellular respiration in most organisms, and hydrogen (\(H_2\)) is not a product (hydrogen is incorporated into water).

Answer:

Carbon dioxide
