Question

10 multiple choice 1 point 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 early and late currents flow inward the late outward current increases in magnitude the early current is at its maximum the early current reverses its polarity

Explanation:

At a membrane potential of 26 mV during an action - potential, the late outward current (usually carried by potassium ions) starts to increase in magnitude as the cell begins to repolarize. As the membrane potential depolarizes to this level, voltage - gated potassium channels start to open more, allowing potassium ions to flow out of the cell, which is an outward current.

Answer:

The late outward current increases in magnitude
