WebSmall, nonpolar, lipid-soluble molecules can pass rapidly through the phospholipids of the plasma membranes. Ions, such as hydrogen ions, and hydrophilic molecules, such as water and glucose, cannot rapidly pass through the phospholipids of the membrane. To move rapidly through the membrane, they must pass through membrane transport proteins. WebThe lipid soluble goes through faster because the cell membrane is phospholipids and can easily diffuse through a fatty membrane. The effect of osmosis on cells Osmosis is simply the diffusion of water. Anytime water flows in or out, it’s called osmosis. The water flows to wherever there is more solute. 1.

Web1) Random movement. sometimes phospholipids acquire enough energy to just move. This depends entirely on factors like temperature, whether there's cholesterol nearby, and whether the phospholipid has saturated or unsaturated tails. 2) Proteins can either … WebWater and lipids are the two major types of solvent in the body.
