FAQs on Electron Transport Chain (ETS) Video Lecture - Biology Class 11 - NEET

1. What is the main function of the Electron Transport Chain (ETS)?

Ans. The main function of the Electron Transport Chain (ETS) is to generate ATP, the energy currency of the cell, through the process of oxidative phosphorylation.

2. How does the Electron Transport Chain (ETS) work?

Ans. The Electron Transport Chain (ETS) works by transferring electrons from electron donors to electron acceptors, creating an electron flow. This flow of electrons is used to pump protons across a membrane, creating a proton gradient. The energy released from the flow of protons back across the membrane is then used to generate ATP.

3. What are the components of the Electron Transport Chain (ETS)?

Ans. The components of the Electron Transport Chain (ETS) include protein complexes I, II, III, and IV, as well as coenzyme Q and cytochrome c. These components work together to transfer electrons and protons, ultimately leading to the production of ATP.

4. What happens if there is a disruption in the Electron Transport Chain (ETS)?

Ans. If there is a disruption in the Electron Transport Chain (ETS), the flow of electrons and protons is disrupted, leading to a decrease in ATP production. This can result in a decrease in cellular energy levels and potentially impact various cellular processes.

5. How does the Electron Transport Chain (ETS) relate to cellular respiration?

Ans. The Electron Transport Chain (ETS) is a crucial part of cellular respiration. It is the final step in the process of aerobic respiration, where electrons from molecules like NADH and FADH2 are transferred to oxygen, producing water and generating ATP. Without the Electron Transport Chain (ETS), cellular respiration would not be able to efficiently produce energy for the cell.
