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

They flow out of the thylakoid, providing energy to add a phosphate group to ADP.
They build up in the thylakoid, providing energy to break apart ATP molecules.
They build up in the thylakoid, where they bond to each other to create ATP.
They flow out of the thylakoid, where they stimulate enzymes to break apart ATP.

The result of the hydrogen ions that are split from the water molecules is they flow out of the thylakoid, providing energy to add a phosphate group to ADP. The correct option is A.

What is photosynthesis?

Photosynthesis is a process of producing ATP in the chloroplast of the leaves of the plant. Chlorophyll trap sunlight and water and CO2 get mixed and glucose and oxygen are released.

Energy is present in the body in the form of ATP, and as energy is made it is added to the phosphate group. ADP is adenine diphosphate. So if energy is increased, it is added to the ADP and converted into ATP adenosine triphosphate.

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