Question

Write two differences between breathing and respiration.

Answer 1

Breathing	Respiration
Breathing is a physical process in which oxygen-rich air is taken in and carbon dioxide-rich air is given out.	Respiration is a biochemical process in which glucose is oxidised and metabolic wastes such as carbon dioxide and water are released.
Breathing occurs outside the cells and there is no release of energy.	Respiration occurs inside the cells and involves the breakdown of food using oxygen to convert it into energy.
