Which of the following statements about a chemical synapse is true?
Answer:
During chemical synapse, when the action potential reaches the end of presynaptic neuron, calcium ions enter the presynaptic neuron. Higher calcium concentration inside neuron allows to release neurotransmitters that reach postsynaptic neuron and binds to the receptors on postsynaptic neuron. The binding of neurotransmitters to receptors generates action potential in postsynaptic neuron.
