'Which of the following is not correct about neurotransmitters? they are stored in vesicles after impulses are over they are broken down at the synapse they bind to a receptor on the receiving neuron they are stored in the cell body or soma of the neuron'

37. which among the following is not true for neurotransmitters? (ONLY ONE ANSWER) a. have receptors on the postsynaptic membrane b. are found on electrical synapse c. are typically simple molecules d. are released by vesicle fusion at the axon terminal

Neurotransmitters are defined by four essential characteristics. These are: Neurotransmitters are synthesized within presynaptic neurons. Depolarization of a neuron results in the release of a neurotransmitter, which exerts a multitude of actions on the postsynaptic neuron. Their action on postsynaptic neurons can be replicated by administering a drug that mimics the activity of the endogenous neurotransmitter. Their action in the synaptic cleft is terminated by a specific action. A, C, and D only
