The energy derived from the movement of h + ions down an electrochemical gradient from the intermembrane space into the matrix is used to drive the synthesis of atp. how many h + ions must be moved into the matrix for the synthesis of 1 atp?

3

Explanation:

These are the 3 hydrogen ions that must carry the needed energy which ATPase must trap from,to synthesize 1 ATP molecule from the :

Reaction of ADP with inorganic Phophate .ADP +Pi - 1ATP

These hydrogen ions were delivered by NAD as NADH and as FADH ,and striped and broken down to

Protons/hydrogen ions and electrons.

Oxygen is the final aceptor of electrons.
