Both graphs depict different phases of electrical activity in cells. Top Graph: Region 65: Located on the left side of the graph, this vertical segment shows a sharp rise in membrane potential, indicating a rapid depolarization phase where the potential becomes significantly more positive. Region 66: Following the sharp rise, this curved segment shows a gradual decline in membrane potential, representing the repolarization phase where the membrane potential returns to a more negative value, approaching the baseline level. Bottom Graph: Region 67: This segment is located at the baseline and shows the initial membrane potential before any significant changes. This stable phase represents the resting state of the membrane. Region 68: This upward curve shows the rapid rise in membrane potential, indicating depolarization. The potential becomes more positive, reaching its peak value, which is essential for initiating cellular activity. Region 69: Following the peak, this downward curve indicates repolarization, where the membrane potential decreases, returning towards the baseline. This phase is crucial for resetting the membrane potential after depolarization.
