What is Respiration?
Respiration is the process of taking oxygen from the environment for the blood cells of the living organism. It is converting glucose in the body and oxygen taken by living beings into carbon dioxide and water. This process does not occur in plants. It helps in the breakdown of elements during breathing. It is a catabolic process in which glucose and oxygen are converted into carbon dioxide and water. It is an exothermic process that does not require sunlight. Respiration occurs in the mitochondria of the cell. Its chemical reaction is:
C6H12O6 + 6O2 ⇒ 6CO2 + 6H2O
Difference Between Photosynthesis And Respiration
The main difference between photosynthesis and respiration is: Photosynthesis is the process of converting light energy into chemical energy which is observed in green plants and some bacteria due to the presence of chlorophyll. It occurs in the chloroplasts in the presence of sunlight. It is an anabolic process that requires carbon dioxide, sunlight, and water to produce glucose, oxygen, and water. It is an endothermic reaction. Respiration is the process by which living organisms convert energy for the use of the cells in the absence of chlorophyll. It occurs in the mitochondria of the cell. It does not require the presence of sunlight. It is a catabolic process that requires glucose and oxygen to produce carbon dioxide and water. It is an exothermic reaction.
