How are photosynthesis and cellular respiration related?

Question

Julian Aguilar · Accepted Answer

They are essentially the reverse of each other.

Photosynthesis is an endothermic reaction that results in the production of glucose and oxygen through the reaction of energy, carbon dioxide, and water. #"glucose "+ " oxygen" " (+ energy)" ->" carbon dioxide " + " water"# #"C"_6"H"_12"O"_6 + 6"O"_2 -> 6"CO"_2 + 6"H"_2"O"# The process of respiration is the synthesis of energy from glucose; it is exothermic, utilizing oxygen and glucose to produce water, carbon dioxide, and energy. #"carbon dioxide " + " water" + " energy" -> " glucose" + "oxygen"#>#6"CO"_2 + 6"H"_2"O" -> "C"_6"H"_12"O"_6 + 6"O"_2# The equations show that they are basically the opposite of one another. The way they are used also differs: while photosynthesis is exclusive to plants, respiration takes place in the mitochondria of all living cells. Plants use photosynthesis to produce their own glucose, which they then use through respiration to get usable energy. Glucose can be stored for use in a variety of ways beyond respiration. I hope this is useful.

undefined As a result, the products of one process are the reactants of the other, forming a cyclical relationship vital to the survival of most life forms on Earth. Photosynthesis and cellular respiration are related through the exchange of gases and the flow of energy and matter within ecosystems. During photosynthesis, plants use carbon dioxide and water to produce glucose and oxygen, while during cellular respiration, organisms break down glucose and oxygen to produce carbon dioxide, water, and ATP.
