The Portion of the Transmembrane Receptor That Binds to Hydrophilic

Question

The portion of the transmembrane receptor that binds to hydrophilic messengers is termed the
A)receptor-binding domain.
B)transmembrane domain.
C)ligand-binding domain.
D)intracellular domain.

Accepted Answer

The portion of the transmembrane receptor that binds to hydrophilic messengers is called the ligand-binding domain. This is where the receptor recognizes and interacts with the specific messenger molecule. The receptor-binding domain refers to the part of the protein that interacts with the ligand-binding domain of another molecule, while the transmembrane domain and intracellular domain are other regions of the receptor that are not involved in binding to messengers.
