Ion Channels

Ion channels are transmembrane proteins that aid in the maintenance of inorganic ion homeostasis within the cell by selectively importing and exporting ions across the plasma membrane. These proteins form a hydrophobic pore across the membrane to connect the extra cellular matrix with the cytosol of the cell. These channels are not continually open; rather they are controlled by external/internal chemical, electrical, or mechanical factors. These external factors cause a change in the conformational shape of the channel truing the flow of ions on or off. …
