Question

multiple choice question
what is synthesized in the cytoplasm of the synaptic knob and stored in synaptic vesicles?
calcium ions
neurotransmitters
sodium ions
oostsynaptic membrane receptors

Explanation:

Neurotransmitters are synthesized in the cytoplasm of the synaptic knob and stored in synaptic vesicles for release into the synaptic cleft to transmit signals to the next neuron. Calcium and sodium ions are involved in the signaling process but not stored in synaptic vesicles. Postsynaptic membrane receptors are located on the receiving - neuron side, not synthesized and stored in the synaptic knob's vesicles.

Answer:

B. Neurotransmitters
