When charged, medium-sized molecules like glucose and amino acids move across a membrane from high to low concentration, the following process has occurred.
A) simple diffusion
B) osmosis
C) active transport involving membrane proteins
D) facilitated diffusion

Question

Quizplus · Accepted Answer

Facilitated diffusion is the process by which molecules that cannot directly diffuse across the membrane pass through special protein channels, moving from an area of high concentration to an area of low concentration without the use of energy. This applies to molecules like glucose and amino acids.
