B) primary active transport
C) secondary active transport
D) diffusion through a protein channel
E) facilitated diffusion

Question

Quizplus · Accepted Answer

Glucose enters most cells through facilitated diffusion, in which it moves down its concentration gradient through a protein channel. This type of transport does not require energy, and the protein channel helps to facilitate the movement of glucose through the hydrophobic interior of the lipid bilayer.
