I have only idea that Antibodies are produced by a type of white blood cell called a plasma cell. Antibodies can occur in two physical forms, a soluble form that is secreted from the cell, and a membrane-bound form that is attached to the surface of a B cell and is referred to as the B cell receptor (BCR). Some antibodies act by binding to certain essential enzymes in the target bacteria. So, I want to know that how might these antibiotics influence the chemical reactions controlled by the enzymes and what is the anticipated effect on the bacteria? Any idea regarding my doubts, please share with me.
