  • Question 17
    900 seconds
    Q.

    Acetylcholine, a common neurotransmitter, is synthesized in the pre-synaptic end of a neuron and released into the synaptic cleft as shown in the illustration above. What would be a likely result of an increase in the amount of acetylcholinesterase present in the synaptic cleft?

    answer choices

    More sodium would enter the sodium/potassium ion channels of the postsynaptic dendrite

    More potassium would enter sodium/potassium ion channels of the postsynaptic dendrite

    Fewer sodium/potassium ion channels would be opened in the postsynaptic dendrite

  • Question 18
    900 seconds
    Q.

    Lidocaine is a local anesthetic that works as a temporary pain reliever. Lidocaine works by binding to voltage sensitive Na+ gates on pain receptors and prevents the gates from opening. Which of the following best describes why Lidocaine is an effective anesthetic?

    answer choices

    Lidocaine limits sodium influx, which increases the production of presynaptic vesicles.

    Lidocaine increases sodium influx, which stimulates the propagation of the action potential.

    Lidocaine decreases sodium influx, which decreases the propagation of the action potential.

    Lidocaine increases sodium influx, which decreases the release of neurotransmitters.
