Essay A: This essay must be written in full sentences at the College level. If you have covered all parts, you will likely have 8-10 sentences or 2 significant paragraphs. Make sure you are detailed and define all relevant terms and explain their role in the process.   An action potential is a signal that causes a cell to increase its intracellular calcium. In this essay, explain where this intracellular calcium comes from in a skeletal muscle fiber and then follow the domino effect of this influx through the power stroke. Hint: be detailed about the activity of the thick and thin filaments and the process of phosphorylation. (HINT Assume the action potential has ALREADY been received and is moving down a membrane at peak voltage… you are dealing with what calcium does inside the cell.)
