- True or False: Neurotransmitters have different shapes.True or false: Neurotransmitters only interact with metabotropuic receptors but neurohormones interact with both ionotroipic and metabotropic receptors.With respect to nerve impulses, the Rising Phase is initiated by binding of neurotransmitters to ligand channels. True False
- Catecholamines are neurotransmitters that are produced in the adrenal glands and are released during a stress response. Some typical effects are increased heart rate, increased blood glucose levels and elevated blood pressure. Examples include dopamine, norepinephrine, and epinephrine. Reserpine is a drug that can control high blood pressure by reducing the number of catecholamine neurotransmitters present in the synapse. Which f the following rows correctly identifies the effect of reserpine in the synapse and the division of the nervous system it affects? Select one: Effect in the Synapse Division of the Nervous System Keeps catecholamines longer Sympathetic nervous system in the synapse b. Effect in the Synapse Division of the Nervous System Inhibits release of catecholamines from the presynaptic neuron Sympathetic nervous system Division of the Nervous System Effect in the Synapse Inhibits release of catecholamines from presynaptic neuron Parasympathetic nervous system d.

- True or false: Manipulating the synthesis of neurochemicals produces only short-term effects in most cases due to sensitive feedback loops for neurochemical production.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…Receptor for epinephrine consists of seven transmembrane helices. T/F
