Want to know:

Which of the following statements on either the rising or overshoot phase of the action potential is false?a. The time from threshold to maximum depolarization is essentially instantaneous (i.e., too fast to be measured accurately with current electronics).b. A positive feedback loop leads to a regenerative depolarization that would increase continuously if unchecked.c. The degree of depolarization is limited in part by the declining driving force on sodium entry.e. The degree of depolarization is limited in part by the inactivation time course for the sodium current.e. The degree of depolarization is limited in part by the activation time course of the potassium current.
