Protein channels are important to facilitate the transport of ions and other larger molecules across the plasma membrane.   Large molecules cannot just diffuse thorough the â¦ membrane. In addition, polar molecules cannot diffuse through the membrane since it would be energetically unfavorable for them to negotiate the hydrophobic interior of the plasma membrane. Therefore, protein channels are essential in membrane transport.
Channel protein A hollow or pore-containing protein that spans a cell membrane and acts as a conduit for small molecules, such as charged particles (ions). Checkpoint One of several points in the cell cycle where the cycle can pause if there is a problem such as incomplete DNA synthesis or damaged DNA.See cell cycle. protein A protein located on the inside of the cell membrane that helps transmit molecular signals into cells. Gene A unit of heredity; a segment of DNA that contains the code for making a specific protein or RNA molecule. Genome (JEE-nome) All of an organism's genetic material.
