Facilitated diffusion across a membrane
WebDuring facilitated diffusion by carrier proteins, when solute concentrations are low, increasing the solute concentration causes a linear increase in the rate of diffusion. However, at high solute concentrations, further increases in the solute concentration no longer increase the rate of diffusion. This means that carrier proteins exhibit ______. WebThe second type of facilitated diffusion utilizes carrier proteins in the membrane and is known as carrier-mediated transport. Unlike the channel proteins, carriers bind to a specific solute on one side of the membrane which causes the carrier to change shape, allowing solute access to the other side of the membrane (think of a revolving door).

Webfacilitated diffusion The plasma membrane forms a pocket that pinches inward, forming a vesicle that contains material from outside the cell. endocytosis A form of passive transport. Molecules move across the plasma membrane by crossing the lipid bilayer. diffusion Requires energy from the cell. Molecules move against their concentration gradient. WebFacilitated Diffusion represents the movement of substances across the membrane that are too big and/or too polar to pass through the membrane. This type of movement is mediated by integral membrane proteins called transport proteins. Unlike simple diffusion, this process of diffusion exhibits saturation, and its rate is directly related to the ...
