Answer: The correct answer is "oxygen is released as byproduct".
Explanation:
Photolysis of water in photosystem II leads to the production of three things:
1. High energy electron
2. Hydrogen ions
3. Oxygen
1. High energy electrons are passed through ETC and help in production of H+ ion concentration gradient. This gradient is used to produce ATP
2. Hydrogen ions directly help in creating the concentration gradient
3. Oxygen is released out of the cell as the byproduct. This oxygen is used in cellular respiration by different organisms.
The oxygen atoms are released back into the air.
• The process by which plants utilize water, sunlight, and carbon dioxide to produce oxygen and energy in the form of sugar is known as photosynthesis.
• At the time of photosynthesis, the plants take in CO2 and water from the soil and air.
• The water gets oxidized within the plant cell, thus, it loses electrons, and the reduction of carbon dioxide takes place thus it acquires electrons.
• This converts the carbon dioxide into glucose and the water into oxygen.
• The plant then discharges the oxygen back into the atmosphere, and stores energy within the molecules of glucose.
Thus, the oxygen atoms get released back into the atmosphere.
