20 cze 2018 · A channel protein is a special arrangement of amino acids which embeds in the cell membrane, providing a hydrophilic passageway 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.
23 kwi 2022 · Channel proteins. Channel proteins are water-filled pores; They allow charged substances (eg. ions) to diffuse through the cell membrane; The diffusion of these ions does not occur freely, most channel proteins are ‘gated’, meaning that part of the channel protein on the inside surface of the membrane can move in order to close or open the pore
Describe the structure and function of pump proteins, including the role of specificity, conformational change and ATP. Compare active transport using a pump protein to facilitated diffusion using a channel protein.
Which of the following best describes the characteristic feature of channel proteins compared to carrier proteins?
