process where calcium ions regulate cellular functions
Calcium signaling, also known as Ca2+ signaling, is a process where calcium ions (Ca2+) act as a signal within cells to regulate various functions such as muscle contraction, neurotransmitter release, and gene expression. When calcium ions enter the cell or are released from internal stores, they bind to proteins and trigger specific cellular responses, making it a crucial mechanism for maintaining cellular activities and overall physiological balance.
