What type of cell transport uses carrier proteins?

Question

Question 11 options:

A)

Active transport

B)

Osmosis

C)

Facilitated diffusion

D)

Passive diffusion

Answer 1

C) Facilitated diffusion

Carrier proteins are used in facilitated diffusion to help transport specific substances across the cell membrane without the expenditure of energy. This process enables the movement of substances down their concentration gradient. Active transport, on the other hand, requires energy and generally involves other types of transport proteins.
