Cellular respiration is the process by which living organisms break down glucose in the presence of oxygen in order to produce energy, carbon dioxide and water is always given off as the by products of the reaction. The process of cellular respiration is very important for living organisms because it is the only way through which they can obtain the needed energy to fuel the life sustaining activities of their cells. The process of cellular respiration also has impact on the environment because the photosynthetic plants depend on the carbon dioxide and water, that is produced as the end product of cellular respiration to carry out photosynthesis. Animals in turn use the oxygen and glucose that is produce by photosynthesis to carry out the process of cellular respiration.
Answer:
All compounds are molecules, but not all molecules are compounds. That is because a molecule can be made up of two atoms of the same kind, as when two oxygen atoms bind together to make an oxygen molecule. However, all compounds are made up of two or more different types of atoms.
