Homework Answers
the right option is
Release of transmitter onto extrasynaptic receptors
because, it reflect the number of transmitter molecules in one synaptic vesicle and the number of postsynaptic receptors available at the synapse.

Question 14 2.5 pts A. Use several sentences to describe Ca2+-based mechanisms underlying neurotransmitter release. B. Assume you are recording from the squid giant synapse and are able to stimulate the presynaptic neuron and record the response in the postsynaptic neuron. Describe a set of experiments (and their results) to demonstrate that Ca2is both necessary and sufficient for neurotransmitter release. State which experiment you describe shows necessity and which shows sufficiency. Use several paragraphs to discuss your proposed experiments, what...

Question 6 0.5 pts The "docking" of a synaptic vesicle at the active zone inside an axon terminal is an important step in making the synaptic vesicle available for release. The docking process involves which of the following events? the neurotransmitter molecules bind to postsynaptic recept O molecules of neurotransmitter are actively transported inside the synaptic vesicle the synaptic vesicle membrane fuses with the synaptic membrane and ruptures O vesicle-associated membrane proteins linking together with proteins associated with the presynaptic...

Psychoactive drugs usually exert their subjective and behavioral
effects by modifying synaptic transmission in one or more of the
following ways: (1) increasing or decreasing transmitter synthesis,
(2) reducing transmitter inactivation by inhibiting enzymatic
breakdown or blocking reuptake, (3) stimulating transmitter
release, and (4) acting as agonists or antagonists at transmitter
receptors on the postsynaptic or presynaptic (i.e., autoreceptors)
cell.
What are 3 targets for psychoactive drugs, including
complementary agonist and antagonist drug actions?
