|
The period of time in which a second action potential cannot be generated, even with a very strong stimulus is called the:
|
|
depolarization
|
|
|
refractory period
|
|
|
inactivation period
|
|
|
repolarization
|
Explanation:
Detailed explanation-1: -The absolute refractory period is a period of time after the initiation of one action potential when it is impossible to initiate a second action potential no matter how much the cell is depolarized.
Detailed explanation-2: -During relative refractory periods, a greater stimulus is required than initially because only some of the voltage-gated channels are open and the cell may be hyperpolarized.
Detailed explanation-3: -During the absolute refractory period of an excitable cell’s membrane, an action potential will not be generated regardless of the strength of the stimulus.
