Sugar to ATP

The cell’s energy currency

An interactive lesson with 5 steps, about 5 minutes: you predict, drag and solve, with instant feedback on every answer. It runs in your browser and needs JavaScript.

What you’ll learn

  • Respiration: glucose + O₂ → CO₂ + H₂O, ΔG ≈ −2870 kJ/mol, captured stepwise.
  • ATP: the cell’s energy currency (~30.5 kJ/mol per split), recycled constantly.

Steps

  1. Burning sugar slowly
  2. A turbine in your cells
  3. Efficiency
  4. Your daily ATP
  5. Why not just glucose?
