Question

The best model for the study of the structure of cell membrane is:

• A. RBC of human
• B. Liver cell
• C. Kidney cell
• D. Muscle cell

Answer 1

Answer: (A)

RBC of human

RBCs lack a nucleus and many other cell organelles. Thus, they are best suited to study cell membranes without any complications. They represent a source from which pure plasma membranes can be easily isolated for biochemical analysis. Studies of the red blood cell plasma membrane provided the first evidence that biological membranes consist of lipid bilayers.

Thus, human RBCs have been useful models for studies of membrane structure.

So, the correct answer is option A.
