The action potential spreads through an axon by depolarizing adjacent membrane to threshold.
- K+ departs the cell after Na+, which enters the cell first. Ions can move freely across the axon membrane because of the difference during the action potential.
- Because sodium contains a positive charge, the neuron becomes more positive and depolarized. Potassium channels take longer to open. As soon as the cell does open, K+ rushes out, reversing the depolarization known as repolarization.
- Sodium channels close during the peak of the action potential when potassium leaves the cell. When potassium ions are effluxed, the membrane potential is lowered or the cell becomes hyperpolarized.
- Outside of the cell, the concentration of Na+ is greater than inside the cell. while the concentration of K+ is is greater inside the cell than outside.

A detailed comparison between all of the above details of photosynthesis to the process or subject of your choice?For example if we are going to do cake we are going to need to get all the ingredients so we could start baking when we start mixing the ingredients the cake is almost ready to be baked. We then put it to a pan and put it in the oven to start to bake, And then we have cake. This is like the process of photosynthesis because photosynthesis takes in sun light and then converts oxygen to glucose. The Cake takes in its ingredients and then it gets bake and it gives us energy
