Question

multiple choice question substances that cannot easily cross the lipid bilayer can still diffuse across the plasma membrane with the help of which of the following? specific transmembrane proteins or peripheral proteins specific glycolipids or glycoproteins specific channel proteins or carrier proteins specific hydrophilic proteins or hydrophobic proteins

Explanation:

Substances that cannot easily cross the lipid - bilayer (such as polar or large molecules) rely on specific channel proteins or carrier proteins for facilitated diffusion across the plasma membrane. Channel proteins form pores and carrier proteins change shape to transport substances. Transmembrane and peripheral proteins have other functions, glycolipids and glycoproteins are mainly for cell - cell recognition, and hydrophilic/hydrophobic nature alone doesn't directly enable diffusion across the membrane in this context.

Answer:

C. Specific channel proteins or carrier proteins
