Puas yog ligand yog agonist lossis antagonist?

Hauv Lub Tsev Tshuaj Kho Mob Kawg kawg peb tau qhia ligands (cov molecules uas khi rau receptors). Ligands uas qhib lub receptor los tsim cov lus teb lom neeg hu ua agonists . Ligands ntawd thaiv agonist cov lus teb nruab nrab (ntau dua li hais txog kev teb cov lus teb los ntawm kev khi nws tus kheej) raug hu yeeb ncuab.
