THE GOOD BAD AND UGLY OF THE IMMUNE SYSTEM

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
These special proteins, secreted by plasma cells, act as antibodies that protect the immune system by targeting antigens (substances that are harmful or perceived as harmful to the body).
A
vaccination
B
immunity
C
immunoglobulins
D
none of the above
Explanation: 

Detailed explanation-1: -Immunoglobulins (Ig) or antibodies are glycoproteins produced by plasma cells. B cells are instructed by specific immunogens, for example, bacterial proteins, to differentiate into plasma cells.

Detailed explanation-2: -B lymphocytes produce antibodies-proteins (gamma globulins) that recognize foreign substances (antigen) and attach themselves to them.

Detailed explanation-3: -Immunoglobulins (Ig) are Y-shaped protein molecules, called antibodies, that are made by plasma cells. An immunoglobulin is made up of 4 parts called chains. There are 2 light chains and 2 heavy chains that are attached to each other by chemical bonds. There are 5 types of immunoglobulins – IgG, IgA, IgM, IgD and IgE.

Detailed explanation-4: -Antibodies are protective proteins produced by your immune system. They attach to antigens (foreign substances)-such as bacteria, fungi, viruses and toxins-and remove them from your body.

Detailed explanation-5: -Antibodies belong to a group of globular proteins of serum/plasma; they are therefore also known as immunoglobulins.
