Electron transport chain - mitochondria Vs chloroplasts

Similarities

  • Both use ATP synthase
  • 2 protons provide enough energy for 3 molecules of ATP
  • Proton Protein pumps across inner membrane of organelle
  • Electron transport chain on inner membrane

Differences

  • Mitochondria use oxidative phosphorylation - Chloroplasts use photophosphorylation
  • Mitochondria uses chemical energy from redox reactions - Chloroplasts use light energy
  • Mitochondria have electron transport chain in cristae - Chloroplasts have it in thylakoid membranes
  • Mitochondria has the co enzyme NAD and FAD - Chloroplasts have NADP
  • Mitochondria have proton gradient from the inter-membrane space to the matrix - Chloroplasts have it from the thylakoid space to the stroma
  • Mitochondria have final electron acceptor of Oxygen and H+ - Chloroplasts have Chlorophyll in cyclic photophosphorylation and NADPH+  in non cyclic photophosphorylation.
