Integral membrane proteins can form channels through which ions such as Na⁺ and K⁺ can diffuse.

Question

Quizplus · Accepted Answer

This statement is true. Integral membrane proteins have hydrophobic regions that embed into the lipid bilayer, forming channels that allow ions and other molecules to cross the membrane. These channels can be selective for specific ions or small molecules based on their size, charge, and other properties. Examples of integral membrane proteins that form ion channels include ionotropic receptors, voltage-gated ion channels, and aquaporins.
