The statement that best describes the role of carbon dioxide in cellular respiration is:
B. Carbon dioxide is formed in the Krebs cycle as the bonds of carbons are broken.
During the Krebs cycle (also known as the citric acid cycle), carbon-containing molecules are broken down, and carbon dioxide is produced as a byproduct.
