The mechanism of ATP synthesis in mitochondria and chloroplasts are almost the same, but there is a big difference: the f1 particle in mitochondria uses 2 H+ ions to synthesize one ATP, whereas in chloroplasts the f1 particle uses 3 H+ ions for the same. What make the difference?

  • Any reference for f1 particle uses 2 protons? – JM97 Mar 12 '17 at 13:43
  • It was mentioned in my text book, local publication. – sreekara Mar 12 '17 at 13:52

  • Does this mean that the ATP synthase works same in both mitochondria and chloroplast. But what I have read is that 1 NADPH in mitochondria is capable of sending 6 H+ ions in to the space between the two membranes of mitochondrial. And it obviously produces 3ATP , so 2H+ for one ATP. – sreekara Mar 12 '17 at 14:09
  • 1 NADPH does not produce exactly 3 ATP – JM97 Mar 12 '17 at 14:16
  • Also NADH is used for atp synthesis not NADPH, and 1NADH pumps 10 protons , not 6 protons, provide any reference please. – JM97 Mar 12 '17 at 14:21

  • Reference: one of our coaching institute's book (akash). – sreekara Mar 12 '17 at 14:28
  • So the book mentioned it wrong I will intimate them the same, and thanks for the link. – sreekara Mar 12 '17 at 14:40
