Propagated Signaling: The Action Potential - Voltage-Gated Sodium and Potassium Conductances Are Calculated From Their Currents
3 important questions on Propagated Signaling: The Action Potential - Voltage-Gated Sodium and Potassium Conductances Are Calculated From Their Currents
By which two factors is the current flow of Na+ and K+ most modulated?
- Conductance of channels
- Electrochemical driving force
What are the main differences between voltage gated Na+ and K+ channels?
Na+ channels become inactive after some time during the depolarization, K+ stays open for the whole duration of depolarization.
What are the three states a voltage gated Na+ channel can be in?
- resting
- activated (first depolarization encounter)
- inactivated (prolonged depolarization)
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
