Agonist - Definition, Types and Quiz | Biology Dictionary
网页2017年5月15日 · An agonist is a molecule that can bind and activate a receptor to induce a biological reaction. The activity mediated by agonists are opposed by antagonists, which inhibit the biological response induced by an agonist.
Agonist - Wikipedia
网页An agonist is a chemical that activates a receptor to produce a biological response. Receptors are cellular proteins whose activation causes the cell to modify what it is currently doing. In contrast, an antagonist blocks the action of the agonist, while an inverse agonist causes an action opposite to that of the agonist.
Agonist - Definition and Examples - Biology Online Dictionary
网页2023年5月29日 · Agonist is a chemical substance that binds with a receptor and activates it to induce the action or response. Agonists have an intrinsic efficacy and affinity for the receptor that results in binding to it. This binding results in changes in the receptor’s functioning in the host cell.
Agonist - an overview | ScienceDirect Topics
网页An agonist is a chemical that binds to and activates a receptor to result in a biological response. A partial agonist binds to and activates a receptor, but is not able to elicit the maximum possible response produced by a full agonist.

Agonists, antagonists, and partial agonists | Pharmacology …
网页Agonists, antagonists, and partial agonists. Receptor ligands can be distinguished on the basis of their potential to initiate a biological response following receptor binding: • Agonists bind to a receptor protein to produce a conformational change, which is necessary to initiate a signal that is coupled to a biological response.
