What are the most common receptors for hydrophilic intercellular messenger molecules?
A) peripheral membrane proteins
B) integral membrane proteins
C) specialized phospholipids within the membrane
D) nucleic acids
E) intracellular proteins

Question

Quizplus · Accepted Answer

Integral membrane proteins are responsible for receiving signals from hydrophilic intercellular messenger molecules. These molecules cannot penetrate the lipid bilayer of the cell membrane due to being water-soluble. Therefore, they bind to specific receptors on the surface of the plasma membrane, which leads to the activation of intracellular signaling pathways.
