Calcium pumps

Calcium pumps are specialized proteins found in cell membranes that help regulate the levels of calcium ions inside and outside of cells. Calcium ions play essential roles in various cellular functions, including muscle contraction, nerve signaling, and overall cell communication. When a cell needs to lower its calcium levels, calcium pumps work by using energy to move calcium ions out of the cell or into storage areas. This process is crucial for maintaining the proper balance of calcium, ensuring that cells function correctly and respond appropriately to changes in their environment.
