WebSep 2, 2015 · 3) Facilitated diffusion is a type of passive transport in which ions/molecules cross the semi permeable membrane because permeases present in the membrane facilitate the transport. Like simple diffusion facilitated diffusion doesn't require metabolic energy and simply occurs across the concentration gradient. WebMay 20, 2013 · It doesn't require metabolic energy as the cell doesn't need to do a thing. Thus the answer is A. Facilitated diffusion is where the cell puts protein channels on its membrane to allow diffusion of things that can't pass through the cell membrane normally or do so really slowly.

WebFacilitated diffusion therefore allows polar and charged molecules, such as carbohydrates, amino acids, nucleosides, and ions, to cross the plasma membrane. Two classes of proteinsthat mediate facilitated diffusionare … WebFacilitated diffusion stops once there is no concentration gradient in water molecules. Once the cell reaches the isotonic state, facilitated diffusion does not take place anymore. Also, if you experimentally replace semipermeable membrane with some impermeable material, it would just stop, since molecules cannot pass mechanical barrier any longer. ffc42n21210s-70sWebFacilitated diffusion across a membrane requires ______________ and moves a solute ______________ its concentration gradient. a. transport proteins . . . up (against) b. transport proteins . . . down c. energy and transport proteins . . . up d. energy and transport proteins . . . down Verified Solution denied party screening dps for all personnel
