Anil claims to his friend Sanvi that respiration and breathing are the same process. What question(s) can Sanvi ask him to make him understand that he is not correct?
Sanvi can ask Anil the following questions to help him understand the difference between breathing and respiration:
(1) Is breathing a physical process or a chemical process? Breathing is only the movement of air into and out of the lungs, while respiration is a chemical process that breaks down glucose to release energy.
(2) Does breathing itself release energy from food? No, breathing only brings oxygen into the body, but respiration uses that oxygen to break down glucose and release energy.
(3) Where does breathing occur and where does respiration occur? Breathing occurs in the lungs, while respiration occurs inside cells throughout the body.
Explanation
The chapter clearly distinguishes between breathing and respiration. Breathing is a physical process involving inhaling and exhaling air. Respiration is a chemical process where oxygen is used to break down glucose into carbon dioxide, water, and energy. The chapter states: 'Breathing is a physical process, while respiration is a chemical process that occurs inside the body. Both the processes are essential for our survival!'
Solution Steps
Breathing is a physical process involving movement of air; respiration is a chemical process that breaks down glucose to release energy
Breathing only brings oxygen into the body; respiration uses oxygen to break down glucose and release energy
Breathing occurs in the lungs; respiration occurs inside cells throughout the body
