Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What type of transport uses transport (channel) proteins to help molecules move from higher to lower concentrations?
A
Protein Pumps
B
Diffusion
C
Facilitated Diffusion
D
Osmosis
Explanation: 

Detailed explanation-1: -“Facilitated diffusion is a type of diffusion in which the molecules move from the region of higher concentration to the region of lower concentration assisted by a carrier.”

Detailed explanation-2: -Facilitated diffusion. Facilitated diffusion is a process by which solutes diffuse across membranes that they wouldn’t normally get through on their own. They pass through with the aid of transport proteins.

Detailed explanation-3: -All channel proteins and many carrier proteins allow solutes to cross the membrane only passively (“downhill”), a process called passive transport, or facilitated diffusion.

Detailed explanation-4: -In facilitated diffusion, molecules diffuse across the plasma membrane with assistance from membrane proteins, such as channels and carriers.
