FAQs on Why do we Respire Cellular Respiration? Video Lecture - Science Class 7
| 1. Why do we respire? |  |
Ans. We respire to obtain energy for our body. Respiration is the process by which our body cells break down glucose and convert it into energy in the form of ATP (adenosine triphosphate). This energy is necessary for various physiological processes in our body, such as muscle contraction, maintaining body temperature, and carrying out daily activities.
| 2. What is cellular respiration? | |
Ans. Cellular respiration is the process by which cells convert glucose and oxygen into carbon dioxide, water, and energy in the form of ATP. It occurs in the mitochondria of the cells and is a vital process for the survival of organisms. Cellular respiration consists of three main stages: glycolysis, the citric acid cycle, and the electron transport chain.
| 3. How does cellular respiration occur? | |
Ans. Cellular respiration occurs in three main stages: glycolysis, the citric acid cycle (also known as the Krebs cycle), and the electron transport chain. During glycolysis, glucose is broken down into pyruvate molecules, producing a small amount of ATP. In the citric acid cycle, the pyruvate molecules are further broken down, releasing carbon dioxide and generating more ATP. Finally, the electron transport chain uses electron carriers to produce a large amount of ATP by transferring electrons and generating water as a byproduct.
| 4. What is the significance of cellular respiration? | |
Ans. Cellular respiration is crucial for all living organisms as it provides the necessary energy for various biological processes. It is the primary pathway through which organisms obtain energy to carry out essential functions such as growth, movement, reproduction, and maintaining homeostasis. Without cellular respiration, organisms would not be able to survive and function properly.
| 5. How is cellular respiration related to breathing? | |
Ans. Breathing and cellular respiration are closely related processes, but they are not the same. Breathing, also known as respiration, is the process of inhaling oxygen and exhaling carbon dioxide. It is the means by which oxygen is brought into the body and carbon dioxide is removed. On the other hand, cellular respiration is the process occurring within the cells, where oxygen is used to break down glucose and produce energy. Breathing supplies the oxygen required for cellular respiration, and the byproduct of cellular respiration, carbon dioxide, is exhaled during breathing.
