Place the following generation of action potential steps in order: 1) sodium channels are inactivated.
2) voltage-regulated potassium channels open and potassium moves out of the cell, initiating repolarization.
3) sodium channels regain their normal properties.
4) a graded depolarization brings an area of excitable membrane to the threshold.
5) a temporary hyperpolarization occurs.
6) sodium channel activation occurs.7) sodium ions enter the cell and further depolarization occurs.

6) sodium channel activation occurs.

4)a graded depolarization brings an area of excitable membrane to the threshold.

7) sodium ions enter the cell and further depolarization occurs.

1)sodium channels are inactivated.

2) voltage-regulated potassium channels open and potassium moves out of the cell, initiating repolarization.

3) sodium channels regain their normal properties.

5) a temporary hyperpolarization occurs

Explanation:

action potential occurs when the differences in the concentrations of ions on opposite sides of a cellular membrane lead to a voltage of a specific cell location rapidly rises and falls.

The steps involved in this generation are;

First of all the sodium-gated channel activation occurs due to inflow of Na, this is called depolarization. A graded depolarization brings an area of excitable membrane to the threshold. More sodium ions enter the cell and further depolarization occurs. After which the sodium channels are inactivated due to the opening of voltage-regulated potassium channels and potassium moves out of the cell, returning it to it initial resting phase initiating repolarization. sodium channels regain their normal properties. a temporary hyperpolarization occurs which is a transient negative shift after an action potential occurs.
