3. Judging from your results, what time period after the first action potential best describes the relative refractory period(the time when a second action potential can be generated only if the stimulus intensity is increased)?4. At what interval between stimuli did the second action potential fail, regardless of the stimulus intensity?5. What is the absolute refractory period for this neuron?
1.Define inactivation as it applies to a voltage-gated sodium channel.Your answer:Inactivation of voltage-gated sodium channel refers the status that it can not diffuse Na+.2. Define the absolute refractory period.Your answer:3. How did the threshold for the second action potential change as you further decreased the interval between the stimuli?4. Why is it harder to generate a second action potential during the relative refractory period?
