Diffusion Is a passive process of transport. A single substance tends to move from an area of high concentration to an area of low concentration until the concentration is equal across a space. Facilitated transport Facilitated diffusion is the process of spontaneous passive transport of molecules or ions across a biological membrane via specific transmembrane integral proteins. Channels The integral proteins involved in facilitated transport are collectively referred to as transport proteins, and they...

What is the difference between passive and active transport? Provide an example of a transport protein involved in the passive transport of K+, and one protein involved in the active transport of K+ across the plasma membrane and explain the direction of the flow of K+ in each case (from inside the cell to the outside, or from the outside of the cell to the inside). Also explain for each of your examples if the transport is uniport, symport, or...
