Which are the two types of membrane proteins in RBC membranes?

The main idea is that RBC membrane proteins fall into two broad classes: integral proteins that are embedded in the lipid bilayer and often span the membrane, and peripheral proteins that attach to the membrane surface without spanning it. In red blood cells, integral proteins include band 3 and glycophorin, which cross the membrane and participate in transport or cell-surface properties. Peripheral proteins, such as spectrin, ankyrin, and actin, lie on the cytoplasmic side and connect the membrane to the cytoskeleton, helping maintain shape and integrity. The other options describe terms that either refer to a subset of integral proteins (transmembrane) or describe location or subunits rather than the standard classification of membrane proteins.
