Glycophorin is a heavily glycosylated protein found on the red cell membrane. One or more of the statements in the following list may apply to this protein:
(i) It is a Type I membrane protein
(ii) It is a Type II membrane protein
(iii) It is a Type III membrane protein
(iv) The carbohydrate composition of the protein gives the red cell a hydrophilic surface which allows them to circulate without 'sticking' to other cells or vessel walls.
(v) The carbohydrate composition of the protein gives the red cell a hydrophobic surface which allows them to circulate without 'sticking' to other cells or vessel walls.
(vi) The carbohydrate composition of the protein gives the red cell a surface which allows them to specifically 'stick' to the vessel walls so they can deliver oxygen to respiring tissues.
Ans:
(i) It is a Type I membrane protein
(iv) The carbohydrate composition of the protein gives the red cell a hydrophilic surface which allows them to circulate without 'sticking' to other cells or vessel walls.
