Describe the two stages of the Action Potential. Include (i) the names of the ion channels and whether they are active or passive, (ii) which of these ion channels open during the first stage and which open during the second stage, and the direction ions move, and (iii) the value in mV reached during the two stages.

Describe the relationship between voltage-gated ion channels and the steps of generating an action potential.

ACTION POTENTIAL (AP) ON A NEURON 1. For each of the following channels, indicate what specifically opens it, what specifically closes it, and what goes through (& in what direction) when it is open. •Voltage-gated Na+ channel •Voltage-gated K+ channel 2. What are leak channels? What purpose do they serve in neurons?

Consider an ion for which there are only passive leakage channels. If the membrane potential is farther from the ion’s Nernst potential, the magnitude of the current associated with that ion will be: a. greater b. smaller c. the same d. none of the above And why?

Label a voltage-versus-time diagram of an action potential with the ions involved in each phase, the direction of their movement across the membrane, and the terms depolarize, repolarize, and hyperpolarize.

What would happen to an Action Potential if voltage-gated K+ channels were blocked? A. the Action Potential could not occur B. the Action Potential would not repolarize C. the height of the action potential would be reduced D. the undershoot (after-hyperpolarization) would not occur

Explain an action potential. Include triggering and all channels and flow of ions.
