The type of membrane transport that uses carrier molecules to move substances with the concentration gradient for that substance is
A) simple diffusion.
B) exocytosis.
C) facilitated diffusion.
D) active transport.
E) endocytosis.

Question

Quizplus · Accepted Answer

Facilitated diffusion is a type of membrane transport that uses carrier molecules to move substances with the concentration gradient for that substance. This process does not require energy input from the cell, and the carrier molecules are specific to the substance being transported.
