a

Explanation

Cellular respiration is the mechanism of breakdown of food masterials 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.
