Define depolarization, repolarization, and the action potential.
Madhur L.
Depolarization and Repolarization Depolarization is the process of changing the membrane potential of a cell from a negative value to a positive value. This occurs when there is an influx of positively charged ions, such as sodium ions, into the cell. Repolarization, on the other hand, is the process of restoring the membrane potential back to its resting state. This occurs when there is an efflux of positively charged ions, such as potassium ions, out of the cell. During depolarization, the cell becomes more positive, which allows for the generation and propagation of action potentials. This is an important process in the functioning of neurons and muscle cells. Once the action potential is generated, repolarization occurs to restore the cell to its resting state. The depolarization and repolarization processes are essential for the proper functioning of cells and the transmission of signals. Any disruptions or abnormalities in these processes can lead to various disorders and conditions.
