Calcium-Activated Potassium Channels

Calcium-Activated Potassium Channels are specialized proteins found in cell membranes that help regulate electrical signals in cells, particularly in neurons and muscle cells. When calcium enters a cell, it triggers these channels to open, allowing potassium ions to flow out. This process helps restore the cell's electrical balance after activation, contributing to muscle contraction and nerve signaling. Essentially, they play a crucial role in managing how cells respond to signals, influencing various bodily functions, including heartbeat regulation and the transmission of nerve impulses.
