Question

Give an example of somethings that easily pass through the embedded protein channels, and some things that cannot pass through easily.

Answer 1

Answer:

Small nonpolar molecules, such as O2 and CO2, are soluble in the lipid bilayer and therefore can readily cross cell membranes. Small uncharged polar molecules, such as H2O, also can diffuse through membranes, but larger uncharged polar molecules, such as glucose, cannot.
