Question

Glycoprotein are known to play important role in cell recognition, the specificity of this recognition is provided largely by __________________.

• A. Protein portion of the glycoproteins
• B. Carbohydrate portion of the glycoproteins
• C. Both carbohydrate and protein portion of glycoproteins
• D. Lipid portion of glycoprotein

Answer 1

The correct option is B Carbohydrate portion of the glycoproteins

Carbohydrates are attached to the extracellular face of the plasma membrane in the form of glycoproteins attached to intrinsic or peripheral proteins. These majorly act as receptors for various signalling compounds. Example- antigens present on the surface of RBC are glycoproteins

So, the correct answer is 'Carbohydrate portion of glycoproteins'.
