During photosynthises the energy from sunlight is used to spilt water molecules. What happens to the hydrogen ions that are split from the water molecules?

The question is incomplete, the options are not given and the options is gotten from another websites.

A. They flow out of the thylakoid, providing energy to add a phosphate group to ADP.

B. They build up in the thylakoid, providing energy to break apart ATP molecules.

C. They flow out of the thylakoid, where they stimulate enzyme

D. They flow out of the thylakoid, where they stimulate enzymes to break apart ATP.

The correct option is A.

They flow out of the thylakoid, providing energy to add a phosphate group to ADP.

Explanation:

The correct answer is They flow out of the thylakoid, providing energy to add a phosphate group to ADP because,

During photosynthesis, sunlight split water Molecules into Hydrogen and oxygen electrons in the thykaloid space which form electrochemical gradient. Hydrogen ion passthrough the thykaloid membrane through a protein complex called ATP synthase. The ATP synthase rotate and this form energy that is required to bind ADP and phosphate group together to produce ATP.
