Proteins that extend from the outer surface and traverse the entire RBC membrane to the inner cytoplasmic side are termed __________ membrane proteins.

Question

Quizplus · Accepted Answer

Integral membrane proteins are embedded within the lipid bilayer of the membrane and span the entire width of the membrane. Therefore, the proteins that traverse the entire RBC membrane from the outer surface to the inner cytoplasmic side are integral membrane proteins. Peripheral membrane proteins are located on the outer surface of the membrane and do not extend through the entire membrane. Cytoplasmic proteins are those located on the inner cytoplasmic side of the membrane and also do not extend through the entire membrane. Therefore, options B, C, D, and E are all incorrect.
