Difference between ionophore and aquaporin

WebMovement Across a Membrane and Energy. There are two major ways that molecules can be moved across a membrane, and the distinction has to do with whether or not cell energy is used. Passive mechanisms like diffusion use no energy, while active transport requires energy to get done. WebSep 21, 2016 · Particularly, I would like to call your attention to figure(s) a, b and c. The purple spheres represent sodium ions, and the green ones correspond to potassium ions. Fig a and b represent the same view of the ion binding site, and one can clearly see the slight positional differences of the residues which account for the difference in specificity.

Also known as water channels, aquaporins are … Aquaporins are "the plumbing system for cells". Water moves through cells in an organized way, most rapidly in tissues that have aquaporin water channels. For many years, scientists assumed that water leaked through the cell membrane, and some water does. However, this did not explain how water could move so quickly through some cells.
