Does cellular respiration occur in both plants and animals?

Cellular respiration occurs in both plant and animals. It is the process by which cells convert ADP (adenosine diphoosphate) into ATP (adenosine triphosphate). Plant and animal cells cannot use ADP as a form of energy. The mitochondria within the cells convert ADP into a useable form of cellular energy: ATP. There are three processes involved in cellular respiration. First, carbohydrates (long chains of carbon-based molecules) are broken down into smaller chains, primarily glucose. Then, the mitochandria expels some glucose to other cellular oraganelles, and converts some glucose into ATP. The glucose that was expelled is stored in fat deposit cells for later use. Cellular respiration is an exothermic process that creates energy. The energy is used for cellular functions such as movement of chemical gradients, locomotion and (in the case of plant cells) photosynthesis.
