Question
**Action Potential Phases and Ion Channel Mechanisms** The diagram illustrates the phases of an action potential and the corresponding mechanisms involving Na+/K+ ATPase and voltage-gated K+ and Na+ channels. The phases are labeled A to E on the graph. **Graph Explanation:** - **Y-Axis:** Membrane potential (in millivolts, mV) - **X-Axis:** Time (arbitrary units) - **Phase A:** Resting potential, around -70 mV - **Phase B:** Depolarization, membrane potential rises sharply - **Phase C:** Repolarization, membrane potential decreases back toward resting potential - **Phase D:** Hyperpolarization (undershoot), membrane potential goes below resting level - **Phase E:** Return to resting potential **Ion Channel Diagrams:** - **K (Diagram):** Shows the mechanism with ions moving out of the cell, likely representing a phase involving active transport or ion movement against the concentration gradient. - **L (Diagram):** Displays ion channels allowing ions into the cell, relevant for depolarization. - **M (Diagram):** Indicates the movement of ions restoring resting potential after an action potential. **Matching Phases to Diagrams:** - **A (Choose):** Resting phase, likely associated with Na+/K+ ATPase maintaining polarization. - **B (Choose):** Depolarization phase, related to Na+ channels opening. - **C (Choose):** Repolarization phase, involving K+ channels opening. Refer to these stages and diagrams to understand how action potentials are generated and propagated in neurons through ion exchange and channel mechanisms.
