Final answer:
Channel proteins facilitate the passage of water molecules or ions, which are hydrophilic, not hydrophobic molecules. Option d is incorrectly matched since channel proteins do not typically allow hydrophobic molecules to pass through.
Step-by-step explanation:
The option that is incorrectly matched with its description is d. Channel Protein: allows hydrophobic molecules to pass. Channel proteins typically allow the passage of water molecules or ions, which are usually hydrophilic due to their polarity or charge, rather than hydrophobic molecules. In contrast, hydrophobic molecules can usually dissolve in the lipid bilayer of the cell membrane and diffuse directly through it without the need for a protein channel. Channel proteins are specialized to allow certain ions or small polar molecules to pass through via facilitated diffusion, often based on size and charge. On the other hand, carrier proteins are involved in both active and passive transport, binding specifically to the molecules they transport and undergoing a change in shape to move the molecule across the membrane.
