Which of the following statements regarding facilitated diffusion is correct?
A)It involves a carrier molecule.
B)It requires energy expenditure.
C) It is how protein enters the cells.
D) It is about movement of molecules against its concentration gradient.

Question

Quizplus · Accepted Answer

Facilitated diffusion involves the use of a carrier molecule to transport molecules across the cell membrane. It does not require energy expenditure and is a passive process in which molecules move with their concentration gradient. Protein can enter cells through various mechanisms, but facilitated diffusion is not specifically associated with protein transport. Movement of molecules against their concentration gradient is referred to as active transport, which is a different process from facilitated diffusion.
