What gas is a by-product of aerobic respiration?

• A. Carbon dioxide.
• B. Methane.
• C. Oxygen.
• D. Nitrogen.

Answer: (A)

Aerobic respiration is a metabolic process that occurs in the presence of oxygen. During this process, glucose is broken down to produce energy for the cells. The primary by-products of aerobic respiration are carbon dioxide and water. As cells utilize oxygen to convert glucose into usable energy (ATP), carbon dioxide is produced as a waste product, which is then expelled from the body through the respiratory system. Oxygen, while necessary for aerobic respiration, is consumed rather than produced. Methane and nitrogen are not involved in the typical aerobic respiration process and do not serve as by-products in cells utilizing oxygen to metabolize glucose. Therefore, carbon dioxide is the correct answer, as it accurately represents a key by-product of aerobic respiration in living organisms.
