Covers selective permeability of membranes, diffusion, and facilitated diffusion (including channels and carrier proteins). a concentration gradient from regions of higher concentration to regions of lower concentration. Other factors being equal, a stronger concentration gradient (larger concentration difference between regions) results in faster diffusion. 1.Evolution There are two types; a(n) _____________ binds to the active site of the enzyme; a(n) _____________ binds elsewhere on the enzyme. Passive transport is a naturally occurring phenomenon and does not require the cell to expend energy to accomplish the movement.In passive transport, substances move from an area of higher concentration to an area of lower concentration in a process called diffusion. This does not mean that the two types of molecules do not come into contact with each other. muscle play in its function?
