Question

question 1 which type of passive diffusion is involved in ion transport across cell membranes? answer facilitated diffusion simple diffusion receptor - mediated transport osmosis active transport i dont know yet

Explanation:

Ions are charged particles and cannot pass freely through the non - polar lipid bilayer of the cell membrane. Facilitated diffusion uses transport proteins (channels or carriers) to move ions down their concentration gradient across the membrane, which is a form of passive diffusion. Simple diffusion is for small non - polar molecules, receptor - mediated transport is mainly for larger molecules binding to specific receptors, osmosis is the diffusion of water, and active transport requires energy and is not passive.

Answer:

Facilitated diffusion
