    The waste products are carbon dioxide and water.

    Carbon dioxide can be taken up by plants and other photosynthetic organisms to carry out photosynthesis, which produces glucose, oxygen and water. The glucose from photosynthesis is at the base of the food chain, and usually most organisms of an ecosystem rely on the photosynthetic organisms to produce energy. For most animals, though, build-up of carbon dioxide in the body can be harmful. For example, in humans, accumulation of carbon dioxide in the bloodstream can make the blood acidic, which affects enzyme activity and proteins.

    Water produced from cellular respiration is obviously useful, even if it is removed from the organism. Water can rejoin the water cycle or be used in other parts of the body for cellular processes.

    There are two types of cellular respiration:

    anaerobic respiration and aerobic respiration.

    Aerobic respiration produces carbon dioxide (CO2) and water (H2O) and this is useful as carbon dioxide contributes to the carbon cycle and we can gain water from respiration.

    Anaerobic respiration produces less energy per glucose molecule and produces a toxic substance lactic acid. Lactic acid gives you a painful sensation and this is what oxygen debt is. Oxygen debt is where the oxygen is needed to get rid of lactic acid.

    Aerobic respiration produces, as waste, CO2 (used by plants in photosynthesis) and H2O ( recycled in the water cycle for reuse).
