C. only the sodium gates are open.

Question

Accepted Answer

∻Solution∻ ‖ 1 ⋮ **Understand the context of the question**: The question is related to the action potential of a neuron, which involves the movement of ions across the neuron's membrane. ‖ ‖ 2 ⋮ **Analyze the graph**: At time 'X', the graph shows a peak in membrane potential, which corresponds to the depolarization phase of the action potential. ‖ ‖ 3 ⋮ **Apply knowledge of neuron physiology**: During depolarization, sodium channels open, allowing Na⁺ ions to enter the cell, which causes the membrane potential to become more positive. ‖ ‖ 4 ⋮ **Determine the correct answer**: Since the membrane potential is at its peak, it indicates that sodium channels are open. Potassium channels typically open later to repolarize the membrane. ‖ ∻Answer∻ ⚹ C. only the sodium gates are open. ⚹ ∻Key Concept∻ ⚹ Action potential and ion channel activity ⚹ ∻Explanation∻ ⚹ During the peak of an action potential, sodium gates are open, leading to depolarization of the neuron's membrane. ⚹◊What role do sodium and potassium ions play in the process of depolarization and repolarization in a neuron?⍭ Generate me a similar question◊
