Question

refer to the figure. which of the following is the key event at a membrane potential of -26 mv? the late outward current decreases in magnitude the late outward current increases in magnitude the early current reverses its polarity the early and late currents flow inward the early current is at its maximum

Explanation:

By observing the graph, at a membrane - potential of - 26 mV, the early current (negative - going current) reverses its polarity and starts to become positive. The late outward current is not the main feature at this potential value. The early current shows a transition from negative (inward - flowing) to positive (outward - flowing).

Answer:

The early current reverses its polarity
