How is respiration different from breathing ?

Explanation

**Step-by-Step Text Solution:**

1. **Definition of Breathing**: Breathing is defined as the physical process of inhaling and exhaling air. It involves the mechanical movement of the respiratory muscles and the exchange of gases (oxygen and carbon dioxide) between the atmosphere and the lungs.

2. **Definition of Respiration**: Respiration, on the other hand, is a biochemical process that occurs at the cellular level. It involves the breakdown of glucose (or other organic molecules) in the presence of oxygen to produce energy, carbon dioxide, and water.

3. **Energy Production**: In breathing, there is no energy generated. It is simply the act of moving air in and out of the lungs. In contrast, respiration results in the production of energy (ATP) through the oxidation of food molecules.
