Question

Why is respiration considered to be an energy giving process?

Answer 1

Respiration:

1. Respiration is defined as a process by which oxygen is taken in for the oxidation of food leading to the release of carbon dioxide and energy.

Respiration as an energy-giving process:

1. During respiration, glucose is oxidised to release energy in the form of ATP.
2. Hence, by the breakdown of glucose energy is released in this process.
3. The reaction for respiration can be denoted by the equation: Glucose + Oxygen → Carbon dioxide + Energy + Water
