Can sugar molecules pass through the membrane
Did you know?
WebDec 30, 2024 · Small polar molecules can sometimes pass easily (e.g. ethanol), but more often pass at low rates if at all (e.g. water). However, small nonpolar molecules are able to pass through the membrane with relative ease. The reasons should be self-evident: larger molecules simply cannot fit between the lipid molecules to make their way through. WebThe cell membrane is selectively permeable. It lets some substances pass through rapidly and some substances pass through more slowly, but prevents other substances …
WebDiffusion is the movement of molecules across a membrane from an area of high concentration to an area of low concentration. Is the cell in Model 1 undergoing diffusion? The cell in undergoing diffusion-water is moving from a higher to lower concentration. The sugar molecules are not undergoing diffusion-they are too large. WebThe plasma membrane forms the barrier between a cell and its environment, and it must be permeable enough to allow some substances through it. But it must also be selective about what passes into and out of the cell Examine the following figure. Examine the concentration of sugar molecules in the two solutions.
