Question

Considering the importance of maintained "normal gradients" of Na+ and K+ in the generation of "normal Action Potentials", use Figure C to demonstrate how the Action Potential graph would differ in a patient who had been accidently poisoned by ingesting a dangerous amount of KCL resulting in the ion gradient for K+ being reversed (higher K+ on outside than inside the cell). Provide a logical and reasonable explanation for any changes to the Action Potential graph changes that you suggest Recall that under normal conditions the last step of the Action Potential graph requires proper activity of the Na+ = K+ Pump so that the normal gradients of Na + and K+ across the cell membrane can be maintained. Knowing that this protein requires plenty of ATP to more these two ions and that ATP is made most efficiently in the presence of oxygen, you shouldn't be surprised to learn that the brain needs plenty of oxygen-rich blood brought, to it. But, not everything in blood is "safe
