BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Each B cell produces a single species of antibody, each with a unique antigen-binding site. When a naïve or memory B cell is activated by antigen (with the aid of a helper T cell), it proliferates and differentiates into an antibody-secreting effector cell.

Detailed explanation-2: -B Cells Differentiate Into Antibody-Producing Plasma Cells. As mentioned before, the process of antigen presentation does not only activate the responding T cell but in turn induces the proliferation of the presenting B cell and its subsequent differentiation into memory cells and antibody-producing plasma cells.

Detailed explanation-3: -Where are antibodies produced? Antibodies are produced by B cells (specialized white blood cells). When an antigen comes into contact with a B cell, it causes the B cell to divide and clone. These cloned B cells-or plasma cells-release millions of antibodies into your bloodstream and lymph system.
