The relationship in between photosynthesis and also cellular respiration is such the the commodities of one system are the reactants of the other. Photosynthesis entails the use of power from sunlight, water and carbon dioxide to develop glucose and oxygen. To move respiration provides glucose and also oxygen to develop carbon dioxide and water. Come emphasize this allude even more, the equation for photosynthesis is the opposite of cellular respiration.

Humans, animals and also plants rely on the cycle of moving respiration and photosynthesis because that survival. The oxygen produced by plants throughout photosynthesis is what humans and animals inhale because that the blood to transport to the cells because that respiration. The carbon dioxide developed during respiration is exit from the body and soaked up by tree to help administer the power they need for growth and also development. This is the never ending cycle that sustains life top top earth.


The procedure of photosynthesis is supplied by plants and other photosynthetic organisms to create energy, vice versa, the procedure of to move respiration breaks under the energy for use. Despite the differences between these two processes, there are some similarities. Because that example, both processes synthesize and use ATP, the power currency.

Below are few of the similarities and also differences in between these two systems.

Function/PurposeCapture, convert and also store energy – light power from the sun is converted into chemical energy and stored in the bonds of glucoseRelease energy – chemical energy stored in glucose is exit to develop ATP because that the cell
Reactants/InputsCarbon dioxide, Water and also Light energyGlucose and also Oxygen
Metabolic Process Anabolic - CO2 and energy native ATP and also NADPH are offered to construct glucose moleculesCatabolic - glucose is broken down to create CO2 and also energy in the type of ATP, NADH and also FADH2

The cycle of photosynthesis and also respiration maintains the balance that oxygen and carbon dioxide. Photosynthesis to produce the oxygen come replenish oxygen the is provided up by living organisms throughout respiration. Carbon dioxide produced during respiration is among the reaction plants have to perform photosynthesis.

Photosynthesis and cellular respiration room both part of a mutually advantageous relationship. Moving respiration cannot take place without photosynthesis, and also photosynthesis definitely cannot happen without the aid of the partner.
