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?

$\begingroup$ Any reference for f1 particle uses 2 protons? $\endgroup$– JM97Commented Mar 12, 2017 at 13:43

$\begingroup$ It was mentioned in my text book, local publication. $\endgroup$– sreekaraCommented Mar 12, 2017 at 13:52

$\begingroup$ 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. $\endgroup$– sreekaraCommented Mar 12, 2017 at 14:09

$\begingroup$ 1 NADPH does not produce exactly 3 ATP $\endgroup$– JM97Commented Mar 12, 2017 at 14:16
