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.
The dark reactions of photosynthesis. 1) require ATP and NADPH 2) are light-independent 3) generate sugars. î î î. The relationship between photosynthesis and cellular respiration is often described as cyclic because the products of one process are used as the reactants for the other. Photosynthesis produces carbohydrates from carbon dioxide and water, incorporating light energy into the bonds of the carbohydrates. Cellular respiration, on the other hand, releases energy from the bonds of carbohydrates, producing carbon dioxide and water. î î î.
