what is the role of H+ in the electron transport chain?
 

Dear student,
Refer below for above asked query:-
 In electron transport chain, few of the  multi protein structures  pumps out Hydrogen  ions into the intermembrane space.
As the Hydrogen ions are  pumped out, the concentration of Hydrogen ions  in the intermembrane space gets higher.
So due to this Hydrogen  ions will start flowing back into the Mitochondrial matrix.
Through this movement, the ATP synthase transforms the ADP into ATP.
Thus Hydrogen ions helps in formation of ATP.
