Acts as a neurotransmitter to stimulate the postsynaptic neuron
Where are most neurotransmitters synthesized before release?
Presynaptic terminal
Which of the following is NOT a monoamine neurotransmitter?
GABA
Which amino acid serves as a precursor to serotonin?
Tryptophan
What is the main function of transmitter-gated channels?
Control the electrical activity of the neuron membrane
Which neurotransmitter is categorized as a neuropeptide?
Substance P
What is the primary function of the MAO enzyme in neurons?
To break down neurotransmitters like serotonin, dopamine, and norepinephrine
Which of the following best describes the process of exocytosis?
The bursts of release of neurotransmitters from the presynaptic neuron
What are ionotropic effects in the context of neurotransmission?
The brief on/off effects of neurotransmitters on the postsynaptic neuron
Which type of channels are involved in transmitter-gated or ligand-gated channels?
Receptor-gated channels
Which neurotransmitter is primarily involved in excitatory ionotropic synapses in the brain?
Glutamate
Which of the following neurotransmitters is primarily involved in inhibitory ionotropic synapses in the spinal cord?

What is the primary function of the enzyme monoamine oxidase (MAO)?
To inactivate monoamine neurotransmitters like dopamine and serotonin
Which of the following best describes the process of neurotransmitter release and diffusion?
