What is the difference between respiration and exchange of gases?

Answer and explanation

Correct answer: Gas exchange brings oxygen and respiration releases energy in cells

The governing concept is the distinction between gas exchange and cellular respiration. Gas exchange is the physical diffusion of oxygen and carbon dioxide across respiratory surfaces such as alveoli or plant stomata. Cellular respiration is a chemical process inside cells in which food molecules are broken down to release usable energy. Therefore A is correct; gas exchange alone does not release all cellular energy, and the other options are biologically incorrect.
