Correct order of Electron transfer through Complex IV is

#Unit 1. Molecules and their Interaction Relevant to Biology
  1. cytochrome c  → Fe-Cu center → CuA  →  Oxygen now binds to heme a3 converts  →   O2 to two molecules of water

  2. cytochrome c  → heme a3  →  CuA →  Oxygen now binds to Fe-cu center converts → O2  to two molecules of water

  3. cytochrome c → CuA → Fe-Cu center → Oxygen now binds to heme a3 converts  → O2 to two molecules of water
  4. Fe-Cu center → CuA → cytochrome c → Oxygen now binds to heme a3 converts → O2 to two molecules of water
