QuestionChoice
Active transport is the movement of a substance against its concentration gradient and involves the use of ATP. Glucose is not transported into cells via active transport; it is transported via facilitated diffusion.

GLUT channel: Active transport
QuestionChoice
Glucose is transported into cells via GLUT channels in the plasma membrane. This occurs through facilitated diffusion as glucose moves passively down its concentration gradient through the channel proteins into cells.

a
GLUT channel: Facilitated diffusion
QuestionChoice
Osmosis is the passive movement of water down a water potential gradient. Glucose is not transported into cells via osmosis; it is transported via facilitated diffusion.

GLUT channel: Osmosis
QuestionChoice
Glucose is transported into cells via GLUT channels in the plasma membranes. However, this does not occur through simple diffusion which would involve the passive movement of glucose molecules down their concentration gradient and through the phospholipid bilayer into cells
