The correct answer is: C.Allows large molecules to pass through the cell membrane.

Transport and channel proteins in the cell membrane help facilitate the movement of molecules across the membrane. These proteins are crucial for transporting large, polar, or charged molecules that cannot pass freely through the lipid bilayer, such as glucose, ions, and amino acids.

1.Channel proteins form pores that allow specific molecules or ions to pass through by diffusion.

2.Transport pr...
