Explanation: 

Detailed explanation-1: -There are two main types of B-cells: plasma cells and memory cells. Both types help protect you from infection and disease. Plasma cells: Plasma cells release antibodies in response to antigens. Once a B-cell becomes a mature plasma cell, it can release up to 2, 000 antibodies per second.

Detailed explanation-2: -Antibodies, also known as immunoglobulins, are glycosylated protein molecules present on the surface of B cells (surface immunoglobulins) serving as antigen receptors (BCR), or are secreted into the extracellular space where they can bind and neutralize their target antigens (15).

Detailed explanation-3: -The B cell receptor used in recognition can also be secreted to bind to antigens and initiate multiple effector functions such as phagocytosis, complement activation, or neutralization of receptors.
