Can channel proteins perform active transport
WebMar 5, 2024 · A gated channel protein is a transport protein that opens a "gate," allowing a molecule to pass through the membrane. Gated channels have a binding site that is … WebThe calcium channel proteins are mostly found in skeletal muscles, bones (osteoblasts), brain, peripheral nervous system, spines, neurons, etc. The main function of calcium channel proteins is to transport calcium ions to their destinations. It releases calcium ions and stimulates signal transduction procedures.
