A channel protein is a special arrangement of amino acids which embeds in the cell membrane, providing a hydrophilicpassageway for water and small, polar ions. Like all transport proteins, each channel protein has a size and shape which excludes all but the most specific molecules. A generic channel … See more Depending on whether it is gated or non-gated, a channel protein has a slightly different function. A non-gated channel protein simple allows ions and water to flow freely from one side of a membrane to another. While these … See more When your muscles contract, this is the result of the action of gated channel proteins within your muscle cells. These cells respond to the neurotransmitter acetylcholine, which … See more Most channel proteins are made of several identical protein subunits which form a hydrophilic region in their center. Gated channels function by changing conformation upon … See more
