Question

Molecules that are too large to be moved through the cell membrane can be transported into the cell by
A. osmosis.
B. diffusion.
C. endocytosis.
D. exocytosis.

Answer 1

If the molecules are too large to fit into the cell by means purely of diffusion, then they will be moved into the cell by Carrier or channel proteins. Channel proteins is by facilitated diffusion, going from high to low concentration, with carrier proteins being used for active transport requiring ATP to go from low to high concentrations in the cell.

Hope this helps
