🚀 Quick Overview: The sodium–potassium pump is like a magical swing door for ions in neurons. It ensures the right balance of sodium and potassium ions, all powered by ATP energy, which then allows neurons to send nerve impulses.

Why sodium–potassium pumps? 🤔

Real-world analogy: Imagine trying to bake without the right balance of ingredients. It's the same with neurons; they need the correct balance of sodium and potassium ions to function.

How does it work? 🛠️

  • Pumps 3 sodium ions OUT of the axon.
  • Pumps 2 potassium ions INTO the axon.
  • For every cycle, it needs one ATP for energy (like fuel for a car).
