Q. Respiration is _____.
Solution:
Solution:
Respiration is a catabolic and exergonic cellular process. Respiration, which is also known as cellular respiration, is an enzymatic process of biological oxidation of food materials in a living cell, using molecular O2, producing CO2, H2O and releasing energy in small steps and then storing it in the form of ATP. When required, this ATP is utilised by the cell. Chemically it is a catabolic process and brings about the oxidation and decomposition of organic compounds like carbohydrate, fat, protein in the cells of plants and animals with the release of energy. But all the energy present in respiratory substrate is not released free into the cell.
