question 41

Multiple Choice

An inhibitory postsynaptic potential (IPSP) occurs when

• A) the ligand-gated ion channels with a reversal potential that is more negative than membrane potential open in the postsynaptic membrane in response to transmitter binding.
• B) the ligand-gated ion channels with a reversal potential that is more positive than membrane potential open in the postsynaptic membrane in response to transmitter binding.
• C) metabotropic receptors are activated by transmitter binding.
• D) voltage-gated ion channels open during an action potential.
• E) the ligand-gated ion channels without a reversal potential open in the postsynaptic membrane in response to transmitter binding.
