What is Receptor antagonist?
A '''receptor antagonist''' is a biological repressor [[molecule]]. A receptor antagonist slows down the cell by stopping some of the cell reactions by clogging up the areas that make the cell work. They are sometimes called blockers, such as [[beta blocker]]s. An antagonist is a [[ligand]] which blocks or dampens a biological effect. It acts against an [[agonist]]. They may block [[enzymes]] or passages through [[cell membranes]]. They are part of the [[homeostatic]] system which regulates the body [[physiology]]. Some are made for [[pharmaceutical]] uses. {{-}} {{chem-stub}} [[Category:Drugs]] [[Category:Biochemistry]]
