Question

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?

Answer 1

During the light-dependent reactions, chlorophyll and other light-absorbing molecules capture energy from sunlight. Water molecules are broken down into hydrogen ions, electrons, and oxygen gas. The oxygen is given off as a waste product. Sugars are not made during this part of photosynthesis

Answer 2

Used to synthesise ATP molecules in chloroplast

Explanation:

• The process of photosynthesis takes place in two steps: Light reaction and Dark reaction.
• During light reaction, the presence of sunlight starts the electron transport chain which moves the electron. This leads to a split of the water molecule which forms the oxygen and the protons.
• These protons are accumulated in the thylakoid lumen move out through the ATP synthase Fo unit. This rotates the F1 unit of synthase and converts the ADP to ATP.
