5 At the target, neurotransmitter

Question

• binds to receptor proteins.
• causes membrane channels to open or close.
• causes a change in membrane potential.
• does all of the above.

Answer 1

The correct answer is does all of the above.

Neurotransmitters bind to receptor proteins on the postsynaptic membrane, leading to various effects. This binding can cause ion channels in the membrane to open or close, resulting in changes in membrane potential, which ultimately can influence whether an action potential is generated in the postsynaptic neuron.
