What is Hyperpolarization ?
It is a process of change in cell's membrane potential and it inhibits action potentials by increasing the stimulus and makes it more negative
Which of the following allows the cell to recover from hyperpolarization during an action potential?
The correct answer is Voltage gated potassium channels.
How ?
1. The resting potential of membrane is of - 60 to - 70 millivolts.
2. This makes the interior of cell is negative
3.Action potential begins when depolarization occurs.
4. At this threshold, voltage-gated sodium channels in the membrane open, allowing many sodium ions to rush into the cell
5. After sometime, influx of sodium stops and voltage-gated potassium channels opens bringing the membrane back to its resting state.
