How does alcohol pass the plasma membrane
WebWhen you pass a pin through your skin ,the pinhead is literally much bigger than the individual cell for the pinhead to pass through the said cell membrane.So you can guess the pin must torn out some small veins on its way into your skin,not into an individual cell.Moreover there is no blood inside a cell or cell membrane for it to come out.Hope … WebMar 26, 2024 · Generally, ions (e.g. sodium, potassium) and polar molecules cannot pass through the membrane; they must go through specific channels or pores in the membrane instead of freely diffusing through. This way, the membrane can control the rate at which certain molecules can enter and exit the cell. Endocytosis and Exocytosis
