Answer #1

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.

Select all of the following that are true about a neuron’s function. An action potential occurs if the membrane potential exceeds the threshold potential. A neuron expends no energy while it maintains a resting potential. When the neuron receives a stimulus, sodium ions begin to rush out of the axon. When threshold potential is reached, sodium channels all along the axon open up at once. An axon maintains a positive charge during rest. During the peak of an action potential,...
