Extracted text: The figure below may help in answering some of the questions. 1. What ions are flowing (and in which direction) both during the rising phase and the falling phase of the action potential? 2. What are the values of both the 'y' (vertical) axis and the 'x' (horizontal) axis. 3. If extracellular levels of K+ rose (a condition called hyperkalemia), how would that affect the resting membrane potential? 3
