Match the correct PSP effect with each ion channel action.
A) entry of a negative ion; hyperpolarization
B) entry of a positive ion; hyperpolarization
C) exit of a positive ion; depolarization
D) exit of a negative ion; hyperpolarization
E) B and D are correct.
Question 2
Match up the correct pairing of a receptor type with its action.
A) ionotropic; direct opening of an ion channel
B) ionotropic; more time required to open an ion channel
C) ionotropic; G-protein activation leads to activation of a second messenger
D) metabotropic; second messenger effects that are specific to neuronal communication
E) metabotropic; rapid and short-lived effects on ion channels
