When a Neurotransmitter Molecule Binds Briefly with a Receptor Site

question 25

Multiple Choice

When a neurotransmitter molecule binds briefly with a receptor site, changes occur in the receiving neuron's charge. If there is a voltage shift in a negative direction, then the effect is:

• A) inhibitory, and so the probability that the receiving neuron will fire decreases.
• B) excitatory, and so the probability that the receiving neuron will fire increases.
• C) inhibitory, and so the probability that the receiving neuron will fire increases.
• D) excitatory, and so the probability that the receiving neuron will fire decreases.
