Which characterizes T cell receptors?

Question

Quizplus · Accepted Answer

T cell receptors consist of two polypeptide chains, an alpha and a beta chain, or a gamma and a delta chain. Each chain has a variable region that is responsible for antigen recognition and a constant region that anchors the receptor in the plasma membrane.

Answer: E
 The hydrophilic region is the part of the T cell receptor that extends into the extracellular fluid and the hydrophobic region is the part that anchors the receptor in the plasma membrane. This hydrophobic region is composed of transmembrane domains that span the lipid bilayer.
