Solved in 3 steps
- Which of the following neurotransmitters is associatedwith inhibition exclusively?a. GABAb. acetylcholinec. glutamated. norepinephrineWhy neurotransmitters are important? Cite at least 3 examples.serotonin,y-aminobutyric acid, and dopamine are derived from different amino acids by just one or a very few chemical steps. name one step that is shared in the derivation of all three neurotransmitters?
- Serotonin, norepinephrine, and dopamine are a group of neurotransmitters collectively called monoamines. A lack of these monoamines has been linked to depression. Depression is treated with dru that prolong the effect of these neurotransmitters either by preventing the re-uptake of the neurotransmitters, or by inhibiting the enzyme that breaks down these neurotransmitters. Which of the following statements about neurotransmitters'are true? The table lists the classifications of three antidepressants. Antidepressant Classification fluoxetine selective serotonin re-uptake inhibitor (SSRI) phenelzine monoamine oxidase (MAO) inhibitor amitriptyline tricyclic antidepressant Check all that apply. View Available Hint(s) MAO inhibitors are examples of monoamine antagonists. EFluoxetine inhibits the enzyme that breaks down monoamines. ODopamine plays a role in feelings of pleasure and pain. DA deficiency of serotonin norepinephrine, and dopamine is associated with depression. Some drug…Describe how an action potential in a presynaptic neuron causes a) an excitatory postsynaptic potential; or b) an inhibitory postsynaptic potential in a postsynaptic neuronHow do neurotransmitters directly affect the postsynaptic neuron? A)They cause a change in the electrical potential, exciting the neuron and causing it to fire b)They cause a change in the electrical potential, either exciting or inhibiting the next neuron. C)They cause a change in the electrical potential, inhibiting the neuron and stopping it from fi d)They connect with the appropriate receptor on the postsynaptic neuron
- What is the function of a neurotransmitter?Patients with Parkinson’s disease are sometimes given L-DOPA (3,4-dihydroxyphenylalanine). What neurotransmitter is produced by the decarboxylation of L-DOPA?What is the difference between monoamine neurotransmitters, amino-acid neurotransmitters, and neuropeptides?

Mrs. Kuchinski does not experience euphoria when taking the prescribed dosage. Is she dependent on or addicted to extended-release oxycodone?When do Amino Acid Neurotransmitters occur?John Hughes and Hans Kosterlitz identified the endorphin receptor in frogs, and concluded that animals have a "built in" opioid system. To make sure that endorphins are truly neurochemicals, which of the following question should we ask these gentlemen?
