Question

Antibodies are complex
A. Lipoproteins
B. Steroids
C. Prostaglandins
D. Glycoproteins

Answer 1

Hint: An antibody is a huge, Y-shaped protein delivered by plasma cells that is utilized by the immune system to distinguish and kill microorganisms, for example, microscopic organisms and infections. There is glycosylation at the Fc region (situated at the base of the 'Y')

Complete step by step answer: Antibodies are the proteins (glycoproteins) called immunoglobulins. These are delivered by the lymphocytes in light of passage of an unfamiliar substance or antigen into the body . They are incorporated and discharged by plasma cells that are gotten from the B cells of the immune system. B cells are enacted after binding to their particular antigen and separate into plasma cells. Now and again, the interaction of the B cell with a T helper cell is likewise important. They are utilized by the immune system to recognize and kill unfamiliar articles like microorganisms and infections. Every antibody perceives a particular antigen extraordinary to its objective. Creation of antibodies is known as the humoral immune system.Antibodies are of five kinds, for example lgG, lgM, IgA, lgD, lgE.
Lipoproteins are the micellar complex of protein and lipids.
Steroids are a gathering of lipids obtained from a saturated compound cyclopentanoperhydrophenanthrene, which has a core of four rings.
Prostaglandin is a group of organic compounds derived from basic unsaturated fats and causing a scope of physiological impacts in creatures.
So, the correct answer is option D.

Note: Immunoglobulin otherwise called antibodies are glycoprotein particles delivered by plasma cells (white blood cells). They go about as a basic aspect of the immune reaction by explicitly perceiving and binding to specific antigens, for example, microbes or infections and help in their destruction.The antibody immune response is profoundly mind boggling and extremely explicit. Thus, antibodies are complex glycoproteins.
