  1. Question 1

    Q1. A patient is diagnosed with a condition that affects the nerve cells' electrical properties. Which process is responsible for the rapid repolarization of nerve cells in this situation?

    • A) Sodium-potassium pump activity
    • B) Sodium-chloride cotransport in nerve cells
    • C) Potassium channel opening in nerve cells
    • D) Calcium channel opening in nerve cells

    Answer: Potassium channel opening in nerve cells

    Explanation: Potassium channel opening is responsible for rapid repolarization in nerve cells, while the other options are not directly involved in this process.
