A drug causes pupil constriction, what receptor is it likely an agonist for?
Answer:-
Drugs which cause pupil constriction are agonisy for the muscarinic receptor(M3)
A drug causes pupil constriction, what receptor is it likely an agonist for?
A drug known as an 'agonist' will: Select one: a. an agonist causes agony to the patient b. bind to an antagonist drug O c. bind to the receptor and mimic the endogenous ligand d. bind to the lining of the stomach before being absorbed e. all of these answers describe an agonist drug f.bind close to the receptor binding site for the endogenous ligand, and inhibit the binding of the ligand
QUESTION 4 A drug which is an agonist binds to a receptor and blocks the effects of receptor activity only causes severe side effects augments recpetor activity and produces a therapeutic response is metabolized to an inactive form
What is a drug receptor? What are the major types and how do they differ? What’s the receptor phenomena of upregulation and downregulation? What are the major components of dose-response function and what do they represent? Define the term full, partial, and inverse agonist; allosteric drug; and antagonist.
Concentration What does the graph above show? A dose-response curve for a competitive antagonist A drug-receptor binding curve for a noncompetitive antagonist A dose-response curve for a partial agonist A drug-receptor binding curve for a full agonist % ligand binding O O
(c) Define the terms agonist and antagonist and discuss how the breast cancer drug, tamoxifen, acts an antagonist for the human estrogen receptor while estradiol acts a natural agonist for this same receptor. estradiol tamoxifen
A receptor agonist mimics actions of naturally occurring neurotransmitters. An Ach agonist is Curare. O True False
Question 14 1.81 pts A drug binds and activates a receptor of the natural ligand (neurotransmitter). It interferes with the binding site for the principal ligand. Indirect Agonist Indirect Antagonist Direct Agonist Direct Antagonist
True or False? The specific binding of a labelled agonist to its receptor is calculated by subtracting non-specifically bound labelled agonist from the total amount bound labelled agonist.
Often, the effect of a drug gradually diminishes when it is given continuously or repeatedly. Desensitization and tachyphylaxis are synonymous terms used to describe this phenomenon. Desensitization is a general issue with extended treatment with GPCR agonists as phosphorylation of the receptor interferes with its ability to activate second messenger cascades, although it can still bind the agonist molecule. Which of the following would likely be true for an agonist drug binding to a receptor that has become desensitized over...
Select one compound (drug or toxicant) that targets one of the three receptor types(G-protein coupled receptor pathway, A receptor tyrosine kinase pathway, An ion channel pathway ) and discuss the following for the selected compound: The name of the receptor involved The type of ligand that the drug or toxicant presents: Agonist, antagonist Are there natural ligands that interact with the receptor? If so explain the interaction. Provide a brief explanation of the mechanism of the cellular response upon ligand...
