three questions

This week I learned about the sodium potassium pump. I learned how it is used as a electrochemical gradient in the body. As action potential moves throughout the cell acting as a domino effect, it occurs towards the direction of polarization. It occurs before the muscles can be stimulated again and the ionic concentration of the resting potential is restored by the sodium potassium pump. As the sodium enters the cell it has a reversal effect in charge and leads a change in the permeability momentarily. I have been taking my studies in chemistry to the next level. I come in during lunches and work on notes or worksheets. I ask more questions now in class and I read the book and study for about two hours a night at home. I hope to continue this work and make a drastic improvement in my grade.
