Question

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

• A. If both assertion and reason are true and reason is the correct explanation of assertion
• B. If both assertion and reason are true but reason is not the correct explanation of assertion
• C. If assertion is true but reason is false
• D. If both assertion and reason are false

Answer 1

Answer: (A)

If both assertion and reason are true and reason is the correct explanation of assertion

Answer 2

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.
