Question

Will glucose be able to move across a cell membrane by simple diffusion? Why or why not?

Answer 1

No

Explanation:

Glucose cannot move across a cell membrane via simple diffusion because it is simple large and is directly rejected by the hydrophobic tails.

Instead it passes across via facilitated diffusion which involves molecules moving through the membrane by passing through channel proteins.

Here is a video which uses animations to explain how facilitated diffusion works.
