The transport of glucose into most animal cells occurs via:
Simple diffusion
Facilitated diffusion using channel proteins
Facilitated diffusion using carrier proteins
Active transport

Uses carrier proteins
Requires ATP
Occurs only in plant cells
Facilitated diffusion differs from simple diffusion in that it:
