This is the transport of material from the cell by a sac or vesicle that first swallows the material and then pushes it out of the opening in the cell membrane.
This, also known as facilitated diffusion, is the process by which a substance is transported across cell membranes with the help of protein carrier molecules.
What has facilitated diffusion explained?
In facilitated Diffusion, molecules diffuse throughout the plasma membrane using membrane proteins such as channels and carriers. Due to the concentration gradients present in these molecules, they can move down and diffuse intracellularly (or extracellularly).
Facilitated diffusion is the diffusion of solutes by transporting proteins within the plasma membrane. Facilitated diffusion is a type of passive transport. Facilitated diffusion involves transport proteins, but it is still passive transport because the solute moves along a concentration gradient.
