WebHow did the threshold for the second action potential change as you further decreased the interval between the stimuli? The threshold for the second action potential will be higher, which indeed requires increased strength in the stimulus. Why is it harder to generate a second action potential during the relative refractory period? WebDuring the absolute refractory period no second CAP was recorded because: A) the voltage-gated sodium channels can open, but the shock needs to be bigger to produce action potentials. B) the voltage-gated sodium channels are inactivated, so can not open to produce an action potential. granola made with steel cut oats recipe
