FAQs on Net Yield: Aerobic Respiration Video Lecture - Biology Class 11 - NEET

1. What is net yield in aerobic respiration?
Ans. Net yield in aerobic respiration refers to the total amount of ATP (adenosine triphosphate) molecules produced through the process of aerobic respiration. It represents the amount of usable energy obtained from the breakdown of glucose in the presence of oxygen.
2. How is net yield calculated in aerobic respiration?
Ans. The net yield in aerobic respiration is calculated by subtracting the ATP molecules used in the initial steps of glucose metabolism (glycolysis) from the total ATP molecules produced in the entire process. The net yield is then determined by the difference between these two values.
3. What are the main stages of aerobic respiration that contribute to net yield?
Ans. The main stages of aerobic respiration that contribute to net yield are glycolysis, the citric acid cycle (also known as the Krebs cycle), and the electron transport chain. These processes occur within the mitochondria of cells and result in the production of ATP molecules.
4. How does the net yield of aerobic respiration compare to anaerobic respiration?
Ans. The net yield of aerobic respiration is significantly higher than that of anaerobic respiration. Aerobic respiration can produce up to 38 ATP molecules per glucose molecule, while anaerobic respiration (specifically, fermentation) only produces a net yield of 2 ATP molecules per glucose molecule.
5. What factors can affect the net yield of aerobic respiration?
Ans. Several factors can affect the net yield of aerobic respiration. These include the availability of oxygen, the efficiency of the electron transport chain, the concentration of glucose, and the metabolic rate of the organism. Additionally, certain conditions such as hypoxia or low glucose levels can reduce the net yield of aerobic respiration.
