Detailed explanation-1: -Photosynthesis and respiration are reactions that complement each other in the environment. They are in reality the same reactions but occurring in reverse. While in photosynthesis carbon dioxide and water yield glucose and oxygen, through the respiration process glucose and oxygen yield carbon dioxide and water.

Detailed explanation-2: -Cellular respiration can be described as the reverse or opposite of photosynthesis. During cellular respiration, glucose, in the presence of oxygen, is converted into carbon dioxide and water. Recall that carbon dioxide and water are the starting products of photosynthesis.

Detailed explanation-3: -Photosynthesis transforms light energy into chemical energy stored in glucose, and cellular respiration releases the energy from glucose to build ATP, which does the work of life. Moreover, photosynthesis reactants CO2 and H2O are products of cellular respiration.

Detailed explanation-4: -Hence, respiration is said to be the reverse of photosynthesis.

Detailed explanation-5: -Respiration and Photosynthesis are almostopposite processes because photosynthesis removes carbon dioxide from the atmosphere while respiration puts back carbon dioxide. Cellular respiration uses oxygen and has it’s waste product of carbon dioxide (CO2).
