Insulin is a protein hormone with mostly hydrophilic amino acids.Which is the most likely description of its receptor?
A)Peripheral membrane protein
B)Integral membrane protein
C)Specialized phospholipids within the membrane
D)Nucleic acids
E)Intracellular proteins

Question

Quizplus · Accepted Answer

Since insulin is a hydrophilic protein, its receptor is most likely an integral membrane protein that can interact with the hydrophilic portions of the protein. Peripheral membrane proteins do not span the membrane, and specialized phospholipids and nucleic acids are unlikely to be involved in insulin signaling. Intracellular proteins would not be able to interact with extracellular insulin.
