Q. Assertion : $ATP$ acts as the energy currency of the cell.
Reason : $ATP$ can be broken down to release energy wherever and whenever energy needs to be utilised.

Respiration in Plants

Solution:

Cellular respiration is the mechanism of breakdown of food materials within the cell to release energy, and the trapping of this energy for synthesis of $ATP$. The energy released by oxidation in respiration is not used directly but is used to synthesise $ATP$, which is broken down whenever and wherever energy needs to be utilised. Hence, $ATP$ acts as the energy currency of the cell. This energy trapped in $ATP$ is utilised in various energy-requiring processes of the organisms.
