Summary Introduction
Introduction: Receptors are defined as the proteins that have specificity to attach a particular class of families called the ligand. Receptors can be present within the cell or on the cell surface. The attachment of the ligand to the receptor induces chemical changes within the cell and alters normal functioning of the cell.
