Question

Does photosynthesis produce water?

Answer 1

Photosynthesis produces water:

1. Photosynthesis produces water as a byproduct.
2. During photosynthesis, plants take carbon dioxide$\left(C{O}_2\right)$, and water$\left(H_{2}O\right)$ from the air and soil.
3. In the plant cell, carbon dioxide is reduced, which results in the gain of electrons, whereas water is oxidized, which results in the loss of electrons.
4. Water turns into oxygen, and carbon dioxide turns into glucose.
5. The plant then returns the oxygen to the atmosphere, storing the energy within the glucose molecules.
6. When sunlight interacts with six molecules of carbon dioxide and six molecules of water, one molecule of glucose and six molecules of oxygen are formed.
7. The reaction that occurs inside the thylakoid membrane is the splitting of water.
8. This causes the formation of oxygen gas, protons, and electrons, Water splitting is used to replenish the electron supply of photosystem II.
9. The function of water is to release oxygen ($\mathrm{O}$) from the water molecule into the atmosphere as oxygen gas.
10. Water photolysis is the splitting of water molecules.
11. During the light reaction of photosynthesis, chlorophyll loses its electron as a result of which the light is absorbed by it.
12. The water molecule breaks down, giving electrons to chlorophyll to satisfy its electron requirement.
13. Oxygen is also produced in this process of splitting and is released as a by-product.
