Question

which substance is needed for aerobic cellular respiration to occur?

nitrogen

oxygen

carbon dioxide

methane

Explanation:

Aerobic cellular respiration is a process that requires oxygen. It is the process by which cells break down glucose in the presence of oxygen to produce energy (ATP), carbon dioxide, and water. Nitrogen is not directly involved in this process. Carbon dioxide is a product of aerobic respiration, not a reactant. Methane is not related to aerobic cellular respiration in most organisms.

Answer:

oxygen
