What ions are important in the process of neural transmission. Where is each located?

Neurotransmission is the process in which there is release of neuro transmitters via the axon terminals such that they would activate the receptors as well as bind to the receptors that are present on the dendrites of neurons. The ions that are involved in neuro transmission are sodium ions, potassium ions. The events are:

Graded potential: graded potential is the stage in which if the stimulus has open sodium or potassium channels. If there is opening of the sodium channels, the membrane would depolarise. If there is hyperpolarisation of the membrane, when potassium would exit the membrane.
Action potential: action potential travels long distances. If the stimulus is above a certain threshold, there would be opening of the sodium channels and there would be an increase in the sodium channels with the increased flow, that results in an action potential. Also, there is presence of voltage gated calcium channels. These are present at the synaptic cleft, where the receptors are also present.

Put the events of neural signal transmission at the synapse in the order that they occur from first to last. First to Last 1.Action potential arrives at synaptic terminal from axon. 2.Vesicles in sending neuron fuse with the membrane. 3.Neurotransmitters are released into the synaptic cleft. 4.Neurotransmitters bind to receptor proteins on the receiving cell membrane. 5.Ion channels in the receiving neuron are stimulated to open. 6.Chance of action potential in the receiving cell either increases or decreases.

Where are each of our macronutrients (carbohydrates,proteinsand fats) chemically digested? Where does the process for each of them begin? Also note all locations in the GI tract that these processes continue (until each macronutrient has been broken down into components that our cells can absorb).
