Question

Which of the following statements about synaptic transmission is incorrect?

Options

Choose one · Correct answer highlighted

Neurotransmitters are stored in synaptic vesicles. Neurotransmitters cross the synaptic cleft to bind to receptors on the postsynaptic membrane. Neurotransmitters pass freely through the postsynaptic membrane without binding to receptors. Correct Synaptic transmission can be excitatory or inhibitory.

Explanation

Neurotransmitters must bind to receptors on the postsynaptic membrane to transmit signals; they do not pass freely through the membrane.
