What Is the Role of Ion Channels in Cellular Functions?
Ion channels are integral to numerous cellular processes, including:
- Signal transduction: Ion channels participate in the transmission of signals across the cell membrane, such as in neuronal communication. - Muscle contraction: The movement of ions like calcium and sodium through channels is critical for muscle contraction. - Homeostasis: Ion channels help maintain the balance of ions within cells, crucial for cellular homeostasis.
