Electrical excitability in neurons is maintained by a molecular pump which exchanges _____ across the plasma membrane. A) Na⁺ and Cl^- B) K⁺ and A^- C) K⁺ and Cl^- D) Na⁺ and K⁺

Question

Quizplus · Accepted Answer

The molecular pump mentioned is the sodium-potassium pump, which exchanges sodium (Na+) ions for potassium (K+) ions across the plasma membrane, crucial for maintaining the membrane potential and electrical excitability of neurons.
