Action potentials at a chemical synapse
a. travel from presynaptic terminal to postsynaptic membrane.
b. travel from postsynaptic membrane to presynaptic terminal.
c. travel back and forth from presynaptic terminal to postsynaptic
membrane.
d. travel from presynaptic terminal to presynaptic membrane.
e. stop at the presynaptic terminal and are regenerated on the
postsynaptic membrane.

Option-A

Explanation:

The impulse generated in the neuron is transmitted in the form of an electrical signal or action potential which gets converted into a chemical synapse to transmit the signal from one synapse to another synapse.

The junction at which the electrical signal is converted into the chemical signal is called a synapse. The neurons which produce the chemicals called neurotransmitter from the axon terminal is called the presynaptic neuron and the neuron which receives the signal through receptors of the dendrites is known as the postsynaptic neuron.  

Thus, Option-A is the correct answer.

answer:

i honestly don't know. but for being kind and considerate and trying to make people feel better! people like you show the world that their is still always kindness going around. it means a lot to me (and others! ) that you are trying to cheer people up. we need more people like you! < 3 < 3 < 3
