Respiration
श्वसन
In this Class 10 Science topic from the Life Processes chapter, students learn how organisms obtain and use energy through respiration. The topic explains the difference between breathing and cellular respiration, the role of glucose and oxygen, and how energy is released as ATP. It also covers aerobic and anaerobic respiration, the human respiratory system, gas exchange in the lungs, and the production of carbon dioxide, water, and energy during the process.
