Action potential

Equilibrium potential of an ion is defined as membrane potential at which:

Pick C: No net ion movement occurs. Thinking about Action potential in a practical way — what the structure does, or what the process achieves — leads you here. Clinically and academically, the same logic shows up again and again: this is mainly a definition check, and No net ion movement occurs is the standard term or meaning used in Action potential. Hence No net ion movement occurs is correct. Treat this as a building block for the rest of Action potential; neighbouring topics often reuse the same principle. Keep a one-line summary card for this idea and revisit it before the paper; short, repeated review beats long cramming sessions.

Action potential

Overshoot phase of action potential occurs because membrane potential moves toward equilibrium potential of:

Answer: B) Na+. For Action potential, once you lock onto the key mechanism or definition, Na+ is the clear fit. If you restate the concept in your own words, cause and effect line up with Na+ — that is the mechanism or reason the stem is pointing to. So Na+ is the clean, accurate selection. If a similar stem appears later, start from the same core fact and you will land on the same kind of answer. In class notes, highlight this same phrase next to the related diagram so the wording and the picture reinforce each other. When you practise, cover the choices first, write Na+ from memory, then reveal the letter — that habit builds real recall for Action potential.
