Does red blood cell have cell membrane?
2 Answers
Yes they do!
Explanation:
Red blood cells, even though they look weirdly shaped, do have a cell membrane. In fact, cell membranes are vitally important to red blood cells from the point of view of diffusion, active transport and the huge surface area the cell surface membrane provides for that.
RBCs have a biconcave shape, which means that they have a larger surface area of cell membranes than a usual ellipsoid cell. This in turn facilitates oxygen uptake by the RBCs, as the larger surface area an RBC has means that it can receive a much larger amount of diffused oxygen in the lungs than other cells, were other cells to take oxygen in the same manner. Consecutively, this ensures that they can securely transport adequate oxygen to all our cells and keep them alive.
So... yeah, the main point of all this is: yes, RBCs do have a membrane, and they are far more important to them than to other cells. If looked at from an overall view, the main reason your cells are staying alive is because your RBCs have a cell membrane!
Hope this helps :)
Yes it has,and the cell membrane of RBC is specialised in such a fashion that it maintains an impotant role in maintaining the integrity of the shape of the RBC as well as to change its shape to oval while passing bythe squeezing action of the red pulp of spleen.
RBC cell membrane has 4 major proteins,namely,
1 . Ankyrin
2 . Spectrin
3 . Band 3
4 . Band 4.2
when,all 4 elements are defective,RBC becomes spherical in shape in stead of its normal biconcave shape.(Hereditary spherocytosis)
and,when spectrin alone is abnormal,RBC takes a permanent elliptical shape(Hereditary elliptocytosis)
