Question

1. which gas is released as a waste product during cellular respiration?

a) oxygen
b) carbon dioxide
c) nitrogen
d) hydrogen

Explanation:

Cellular respiration is the process by which cells break down glucose to produce energy. The chemical equation for cellular respiration is \(C_6H_{12}O_6 + 6O_2
ightarrow6CO_2 + 6H_2O+\text{energy}\). In this process, glucose (\(C_6H_{12}O_6\)) reacts with oxygen (\(O_2\)) to produce carbon dioxide (\(CO_2\)), water (\(H_2O\)), and energy. Oxygen is consumed (not released) in cellular respiration. Nitrogen and hydrogen are not the waste products of cellular respiration. Carbon dioxide is released as a waste product.

Answer:

B. Carbon Dioxide
