Question

Quizplus · Accepted Answer

Molecules that bind to a receptor and trigger signaling pathways are called agonists. Agonists activate the receptor and mimic the function of the endogenous ligand, whereas antagonists bind to the receptor but do not activate the signaling pathway. IRE-binding proteins and promoters are not related to receptor binding and signaling.
