Which group(s) of organisms uses cellular respiration to release energy from organic molecules?
saw5 [17]

The cells of animals, plants, and fungi, as well as those of algae and other protists, all engage in cellular respiration.

  • Cellular respiration is the process that all living things use to convert organic molecules into energy.
  • The chemical process that breaks down food molecules to produce adenosine triphosphate, which is used for energy, is known as cellular respiration (ATP). As a result, organisms can now use energy from food molecules to perform everyday tasks.
  • Oxygen is normally present when cells respire. This is called aerobic respiration. Anaerobic respiration occurs when oxygen is absent or present in very small amounts.
  • Anaerobic respiration is essential to the life of some organisms, including many bacteria. Yeast and some bacteria use an anaerobic respiration process known as fermentation. The cellular respiration equation describes the process by which glucose molecules combine with oxygen to produce energy.

Therefore, all most all organisms use cellular respiration.
