Concept explainers
Interpretation:
One example for the drug which can act as an agonist and one example for the drug which can act as an antagonist for the acetylcholine have to be listed.
Concept Introduction:
Drugs: Drugs are molecules which are taken from an external source to change the normal functioning of the body. The action of drug is in molecular level and the design of many drugs are in such a way that it mimics a particular neurotransmitter or hormone. Drugs bind with receptors showing an increased or decreased effect.
There are two types of drugs and they are agonist and antagonist.
Examples for agonist are black widow spider and nicotine whereas examples for antagonist are tubocurarine, atropine

- Give 2 examples of drugs which target neurotransmitter release or reuptake.(expect from cocaine and Prozac). Explain the mechanisms of action.arrow_forwardA patient has been exposed to the organophosphate pesticide malathion,which inactivates acetylcholinesterase. Which of the following symptoms would you predict: blurring of vision, excess tear formation, frequent or involuntary urination, pallor (pale skin), muscle twitching, orcramps? Would atropine be an effective drug to treat the symptoms?(See Clinical Impact 16.2 for the action of atropine.) Explain.arrow_forwardResearch the effects of synthetic cathinones on specific receptors of the brain and how the transmission of action potentials is altered. Be sure to focus only on how the action potential transmission is impacted by the drug. Be sure to provide an APA citation.arrow_forward
- Sarin is an inhibitor of acetylcholinesterase. Draw a mechanism that shows this.arrow_forwardCorrect the following false statement: "Any cell that has the acetylcholine receptor will have the same response as any other cell that also has the acetylcholine receptor when exposed to acetylcholine". Explain why this statement is false.arrow_forwardexplain what does hisatmine and adetycholine mimic. within smooth muscle receptors. what do they bind and what do they activate.arrow_forward
- Briefly describe the proposed mechanism of CNS depression by benzodiazepines. Give examples of most commonly used benzodiazepines. What side effects or clinical problems have to be monitored?arrow_forwardMake a schematic diagram for the synthesis, storage, release, and degradation of acetylcholine.arrow_forwardFentanyl is an opioid similar to morphine, except, according to the CDC, it is up to 50 times stronger than heroin and 100 times stronger than morphine. Discuss the effects of fentanyl on specific receptors and how the transmission of action potentials is altered. Be sure to focus only on how the action potential transmission is impacted by the drug. Be sure to provide an APA citation.arrow_forward
- The endogenous ligand for an ion channel causes the influx of 50 Na+ ions per second. This ion channel has constitutive activity of 10 Na+ ions per second. If drug A binds to the ion channel and causes the influx of 50 Na+ ions per second, which of the following categories best describes drug A? Group of answer choices full agonist antagonist partial agonist inverse agonistarrow_forwardExplain in detail Muscarinic receptors in regards to the hisamine agonist. How do they cause smooth muscle contraction. Provide mechanismarrow_forwardUnder anesthesia, acetylcholinesterase inhibitors can be given in combination with blockade of muscarinic receptors. Explain the purpose of the two treatments.arrow_forward
