At the onset of a muscle contraction, the presence of calcium triggers the opening of the Na-K channels in the membrane. Potassium is a calcium inhibitor, so as the potassium flows out of the cell, it eventually reduces the presence of calcium. This causes the closure of the Na-K channel (negative feedback mechanism). In a hypokalemic state, the lack of sufficient K doesn't inhibit the calcium channel, and in turn doesn't properly terminate the muscle contraction at the cellular level.
In your first sentence switch witch to which. In problem 1 t the end change developpe to develop. In problem 3 the “WE” should not be capitalized. Only the w. At the end of problem 3 ulsee, I don’t know if you were doing unless or you’ll see or useless, but whichever one it is change it to one of those. Spielberg needs to be capitalized. In problem 5 at the end change ended with needed. In problem 6 at the beginning change probes to problems. Other than that it looks great! Coming from a 7th grader❤️
