Textbook Question
Chapter 10, Problem 28RQ
Many potent insecticides contain toxins, called organophosphates that interfere with the action of the enzyme acetylcholinesterase. Ivan is using an insecticide containing organophosphates and is very careless. Because he does not use gloves or a dust mask, he absorbs some of the chemical through his skin and inhales a large amount as well. What signs would you expect to observe in Ivan as a result of organophosphate poisoning?

A 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.

What signs would you expect to observe in Terry as a result of organophosphate poisoning?
When the neurotransmitter acetylcholine (ACh) binds the acetylcholine receptor (a GPCR) on muscle cells, it causes them to contract. ZIGGY, a chemical analog of ACh, also binds to the same acetylcholine receptor on muscle cells, but instead causes the muscle cells to relax. For this reason, it is sometimes prescribed as a muscle relaxer. Explain in 3-4 sentences how ZIGGY could cause muscle relaxation.
How can both ZIGGY and ACh bind the same GPCR? And then how can they have different effects on the cells, despite binding to the same receptor on the same cells?

- A neurotransmitter is a chemical messenger that carries, boosts, and balances signals between neurons, nerve cells, and other cells in the body. a) Identify two disorders that can result in a depletion, damage, or lack of neurotransmitters in our body. Then list and explain at least two neurotransmitters that can result in these disorders developing.arrow_forwardSarin gas is an inhibitor of acetylcholinesterase used in chemical warfare. Briefly (in 1 sentence or less) explain how sarin causes: a) increased urination b) tachycardia (rapid heartrate)arrow_forwardThompson Medical Company manufactures and sells Aspercreme, a topical analgesic. Aspercreme is a pain reliever that contains no aspirin. Thompson’s advertisements strongly suggest that Aspercreme is related to aspirin, however, by claiming that it provides “the strong relief of aspirin right where you hurt.” Is Thompson’s advertisement for Aspercreme false and misleading? Explain.arrow_forward
- "Motor neurons trigger action potentials in muscle cell membranes that open voltage-sensitive Ca2+ channels in T tubules, allowing extracellular Ca2+ to enter the cytosol, bind to troponin C, and initiate rapid muscle contraction", is true or false.arrow_forwardIn atropine poisoning, would you expect the pupils to be dilated or constricted? The skin to be moist or dry? The heart rate to be elevated or depressed? The bladder to retain urine or void uncontrollably?arrow_forwardDiscuss the concept of termination of neurotransmitter action by comparing the mechanisms by which acetylcholine and nitric oxide's actions are terminated. (a) Name the three primary mediators of purinergic receptors. (b) Which one of these mediators is sometimes used to treat supraventricular tachycardia? (c) Explain why the drug in (b) is considered safer than verapamil in the treatment of supraventricular tachycardia?arrow_forward
- Conotoxin is produced by marine cone snails. Among its effects is to block voltage-gated Ca2+ channels in n eurons. A. What anatomical part of a neuron would be affected by conotoxin? B. How would the neuron's action potential be affected by conotoxin? Explain, using at least TWO of the following terms: threshold, depolarization, repolarization, hyperpolarization, summation, IPSP, EPSP, exocytosis C. If conotoxin affected a somatic motor neuron, would this toxin cause muscle weakness or increased muscle tension? Explain why.arrow_forwardIn the disease myasthenia gravis, the human body makes—by mistake— antibodies to its own acetylcholine receptor molecules. These antibodies bind to and inactivate acetylcholine receptors on the plasma membrane of muscle cells. The disease leads to a devastating progressive weakening of the people affected. early on, they may have difficulty opening their eyelids, for example, and, in an animal model of the disease, rabbits have difficulty holding their ears up. As the disease progresses, most muscles weaken, and people with myasthenia gravis have difficulty speaking and swallowing. eventually, impaired breathing can cause death. explain which step of muscle function is affected.arrow_forwardTyrosine came from the Greek word "tyros" which means cheese as it was discovered in cheese by Justus von Liebig, a German chemist in 1846. Tyrosine serves as the precursor for dopamine - the neurotransmitter which is considered as the "reward or pleasure molecule" in our brain. It is also involved in controlling the fine motor movement of our muscles such as those of our hands. Draw the titrimetric profile of tyrosine and calculate its isoelectric pH. [Note: The aromatic hydroxyl group is titratable]arrow_forward
- Organophosphate poisoning is a result of excess acetylcholine at different nerves and receptors in the body because acetylcholinesterase is blocked. Please provide rational to explain how the binding of organophosphate with serine in the acetylcholinesterase enzyme leads to excess accumulation of acetylcholine.arrow_forwardEpilepsy is often treated with a combination of drugs such as carbamazepine and phenytoin (polytherapy). CYP3A4 is induced by phenytoin and carbamazepine. Carbamzeipine is cleared by CYP3A4, but phenytoin is not cleared by CYP3A4. What problems might you expect if (a) carbamazepine is removed or (b) phenytoin is removed from this two-drug regimen.arrow_forwardOrganophosphate poisoning is a result of excess acetylcholine at different nerves and receptors in the body because acetylcholinesterase is blocked.
