the process of molecules going from a high to a low concentration using a specific membrane protein that has no potential energy requirement is termed.
a active transport.
b active diffusion.
c facilitated diffusion.
d simple diffusion.
e osmosis.

Explanation:

Facilitated diffusion is the movement of molecules from an area of high - concentration to low - concentration with the help of a membrane protein and without the input of energy. Active transport requires energy. Simple diffusion doesn't use a specific membrane protein. Osmosis is the diffusion of water. There's no such thing as active diffusion in this context.

Answer:

C. facilitated diffusion
