The process by which molecules such as glucose are moved into cells along their concentration gradientwith the help of membrane-bound carrier proteins is called
A) osmosis.
B) facilitated diffusion.
C) active transport.
D) endocytosis.
E) exocytosis.

Question

Quizplus · Accepted Answer

Facilitated diffusion is a type of passive transport in which molecules move from an area of higher concentration to an area of lower concentration with the help of membrane-bound carrier proteins. This process does not require energy input from the cell. Osmosis is the movement of water molecules across a selectively permeable membrane, while active transport requires energy input to move molecules against their concentration gradient. Endocytosis and exocytosis involve the transport of larger molecules or particles into or out of the cell through the formation of vesicles.
