Calcium Handling

Calcium handling refers to how cells manage calcium ions, which are crucial for many biological processes. In muscles, calcium helps trigger contraction and relaxation. Cells take in calcium when needed and store it in structures called the endoplasmic reticulum. It is released into the cell when signaling occurs, and it's then pumped back out or stored again once its job is done. Proper calcium handling is vital for functions like heartbeats, nerve signaling, and hormone release. Imbalances can lead to various health issues, including muscle weakness or irregular heart rhythms.
