FAQs on Aerobic Respiration Video Lecture - Biology Class 11 - NEET

1. What is aerobic respiration and how does it differ from anaerobic respiration?
Ans.Aerobic respiration is a metabolic process in which cells convert glucose and oxygen into energy, carbon dioxide, and water. It occurs in the presence of oxygen and is more efficient than anaerobic respiration, which occurs without oxygen and produces less energy along with byproducts like lactic acid or ethanol.
2. What are the main stages of aerobic respiration?
Ans.The main stages of aerobic respiration include glycolysis, the Krebs cycle (also known as the citric acid cycle), and the electron transport chain. Glycolysis occurs in the cytoplasm, while the Krebs cycle and electron transport chain take place in the mitochondria. Each stage plays a crucial role in converting glucose into usable energy.
3. Why is oxygen important in aerobic respiration?
Ans.Oxygen is essential in aerobic respiration as it acts as the final electron acceptor in the electron transport chain. This allows for the production of ATP (adenosine triphosphate), the energy currency of the cell. Without oxygen, the electron transport chain cannot function, leading to a halt in efficient energy production.
4. What is the role of ATP in aerobic respiration?
Ans.ATP, or adenosine triphosphate, serves as the primary energy carrier in cells. During aerobic respiration, ATP is produced through the breakdown of glucose. It provides the energy necessary for various cellular processes, including muscle contraction, nerve impulse transmission, and biosynthesis.
5. What are some examples of organisms that rely on aerobic respiration?
Ans.Examples of organisms that rely on aerobic respiration include most animals, plants, and many fungi and bacteria. These organisms utilize oxygen to efficiently convert glucose into energy, which supports their growth, reproduction, and overall metabolic functions.
