So here we are going to start with question number 6 and when we talk about action potential, we know that action potentials are generated in the nervous system.
00:10
And these action potentials as they are generated, they basically very soon are being preceded, not just the full size, but they are being preceded because of the presence of exons.
00:24
And there are some sodium ions which are present and these sodium ions enter through the sodium ions.
00:30
Sodium channels and as they enter they causes the depolarization and the membrane potential at the depolarization changes and because of that they become inactive for repolarization and whenever a second action potential will be generated during this particular time they can be activated so we can say that that a second action potential here at this point of time as because of the depolarization, they are being inactivated for any repolarization.
01:06
So, second action potential cannot be generated here.
01:12
Let's move on to the next question, which is question number 7.
01:17
When we talk about a term which is known as the theoretical maximum frequency, theoretical maximum frequency, which is represented in hertz, can be given as thousand.
01:33
Divided by the refractory period, which is the resting period between both the cycle.
01:41
So it is basically divided by the refractory period equation.
01:46
So this will help in providing a theoretical maximum frequency.
01:51
Let's move on to the eighth question.
01:54
When we talk about multiple cellular events including the refactory period, refactory period is basically the formation of potassium and it occurs during the process of repolarization when repolarization is entering into a phase of hyper -polarization...
