How does ATP synthase obtain the energy to produce ATP? a. Water splits, releasing electrons that flow from the stroma to the thylakoid space and attach to the active site of ATP synthase. b. Electrons from the reaction site center of photosystem II are funneled to ATP synthase, which uses the energy to produce ATP from ADP + Pi. c. A hydrogen ion from NADPH is used by ATP synthase to power the production of ATP from ADP + Pi, and an electron is released, splitting water. d. Hydrogen ions flow down a concentration gradient from the thylakoid space to the stroma through ATP synthase, releasing energy that can be used to produce ATP from ADP + Pi.

Answer:

Option D, Hydrogen ions flow down a concentration gradient from the thylakoid space to the stroma through ATP synthase, releasing energy that can be used to produce ATP from ADP + Pi.

Explanation:

The hydrogen ion released during the breaking of water molecule starts building in the thylakoid space. This causes a difference in concentration across the membrane due to difference in build proton concentration and the charges created across the membrane.  

Potential energy obtained from this set up is collected and stored as chemical energy in ATP through the assistance of enzyme ATP synthase

Option D is correct
