What moves products through a cell membrane?

Answer 1

Diffusion, facilitated diffusion, Osmosis and Active Transport.

Diffusion moves non-polar molecules across the cell membrane down a concentration gradient. Osmosis moves water across the cell membrane through a channel formed by aquaporins called a protein channel, down the water potential gradient. Active moves the non-polar molecules against the concentration gradient, in contrast to diffusion. Lastly, facilitated diffusion moves polar molecules across the cell membrane through creating protein channels in the cell membrane from specific proteins. ETC, glucose transporters bind to form a protein channel for glucose to diffuse through, after which the proteins disperse. That should be all, hope it was of help!

Answer 2

Molecules pass through the cell membrane via processes like simple diffusion (high to low concentration), facilitated diffusion (with the help of transport proteins), or active transport (against the concentration gradient using energy).

Answer 3

simple diffusion :)
