FAQs on Sodium-Potassium Pump Video Lecture - Biology Class 11 - NEET
| 1. What is the sodium-potassium pump? |  |
Ans. The sodium-potassium pump is a vital protein found in the cell membrane of all animal cells. It helps maintain the balance of sodium and potassium ions across the cell membrane, which is essential for various cellular functions.
| 2. How does the sodium-potassium pump work? | |
Ans. The sodium-potassium pump works by actively pumping three sodium ions out of the cell while simultaneously bringing two potassium ions into the cell. This process requires energy in the form of adenosine triphosphate (ATP) and helps establish the resting membrane potential of the cell.
| 3. What is the significance of the sodium-potassium pump? | |
Ans. The sodium-potassium pump is crucial for maintaining the proper functioning of cells. It helps regulate cell volume, establish the electrical potential across the cell membrane, and transport various molecules across the membrane. Additionally, it plays a significant role in nerve impulse transmission and muscle contraction.
| 4. How does the sodium-potassium pump contribute to nerve cell function? | |
Ans. The sodium-potassium pump is essential for nerve cell function as it helps restore the ion concentration gradients after each nerve impulse. By actively pumping sodium ions out of the cell and potassium ions in, the pump helps reset the cell's electrical potential, allowing the nerve cell to generate another impulse.
| 5. Can the sodium-potassium pump be inhibited? | |
Ans. Yes, the sodium-potassium pump can be inhibited by certain chemicals and drugs. For example, cardiac glycosides such as digoxin inhibit the pump's activity, leading to an increase in intracellular sodium concentration. This inhibition can have therapeutic effects in conditions like heart failure, where the increased intracellular sodium concentration enhances cardiac contractility.
