NCERT Solutions for Class 11 Biology Chapter 17 – Breathing and exchange of gases

The chapter provides information about Breathing and exchange of skin. Cells continuously use oxygen (O2) for the catabolic reactions that releases energy from molecules, e.g., breakdown of nutrient molecules like glucose. Thus, O2 has to be provided to the cells constantly. Simultaneously, these reactions releases carbon dioxide (CO2), which is harmful, so it must be removed quickly and efficiently.
The process that helps in the exchange of O2 from the atmosphere with CO2 produced by the cells is called breathing, commonly known as respiration.
