| 1. | Uniporters are involved in many biological processes, including action potentials in neurons.
|
| 2. | If the postsynaptic cell is sufficiently depolarized, an action potential will occur.
|
| 3. | Variation potentials are distinct from action potentials in their cause of stimulation.
|
| 4. | During the absolute refractory period, a new action potential cannot be elicited.
|
| 5. | Neurons generate action potentials resulting from changes in the electric membrane potential.
|
| 6. | Class IB antiarrhythmics decrease action potential frequency by lengthening the repolarization phase.
|
| 7. | The cardiac action potential differs significantly in different portions of the heart.
|
| 8. | This decrease in voltage constitutes the falling phase of the action potential.
|
| 9. | Alt = A plot of action potential ( mV ) vs time.
|
| 10. | The course of the action potential is determined by two coupled effects.
