RBC membrane proteins that are limited to the cytoplasmic surface of the membrane are called __________ proteins.

Question

Quizplus · Accepted Answer

Peripheral proteins are attached to the cytoplasmic surface of the membrane and are not embedded within the hydrophobic core of the lipid bilayer. Integral proteins, on the other hand, span the membrane and have portions that extend into the extracellular and cytoplasmic spaces. Cytoplasmic proteins are a general category that includes both peripheral and integral proteins that are restricted to the cytoplasmic surface of the membrane. Therefore, choice A and D are incorrect, and choice C and E are incomplete.
