Re-polarization in Excitable Cells
In excitable cells, such as neurons and muscle cells, action potentials are generated and transmitted. These action potentials are caused by the movement of ions across the cell membrane.
During an action potential, the cell membrane becomes depolarized as sodium ions enter the cell. This depolarization causes the cell to become more positive, which then triggers the opening of voltage-gated potassium channels.
Re-polarization
Re-polarization is the process by which the cell membrane returns to its resting potential after an action potential has occurred. This process is closely associated with the efflux of potassium ions from the cell.
K Efflux
Efflux means the outward flow. During re-polarization, the voltage-gated potassium channels that opened during depolarization allow K+ ions to flow out of the cell, which causes the membrane potential to become more negative.
As more potassium ions leave the cell, the membrane potential becomes more negative, and the cell returns to its resting state. This process of re-polarization allows the cell to generate another action potential if needed.
Conclusion
In conclusion, re-polarization in excitable cells is closely associated with the efflux of potassium ions from the cell. This process allows the cell to return to its resting potential and generate another action potential if needed.
