Final answer:
Cellular respiration is the process by which organisms release the energy stored in glucose to produce ATP. It is related to photosynthesis as the products of photosynthesis are the reactants of cellular respiration.
Step-by-step explanation:
Cellular respiration is the process by which living organisms release the energy stored in glucose to produce ATP, the molecule that powers cellular work. It occurs in the mitochondria of cells and involves a series of biochemical reactions. Cellular respiration is directly related to photosynthesis as the products of photosynthesis, such as glucose and oxygen, are the reactants of cellular respiration.
