Answer:
Source of O2 in Photosynthesis
Water as a Source of O2
- Photosynthesis is a process in which green plants and some other organisms use sunlight to synthesize foods with the help of carbon dioxide (CO2) and water (H2O).
- During this process, oxygen (O2) is released as a byproduct, which accumulates in the atmosphere and is used by animals for respiration.
- The oxygen that is released in photosynthesis comes from the water molecule, and not from CO2, sugar, or pyruvic acid.
- This is because during the light-dependent reactions of photosynthesis, water is split into oxygen, hydrogen ions (H+), and electrons (e-), which are then used to produce ATP and NADPH.
- This process is called photolysis or water-splitting, and it occurs in the thylakoid membranes of the chloroplasts.
- The oxygen released during photolysis is then released into the atmosphere as a byproduct of photosynthesis.
Conclusion
- Therefore, the correct answer to the question is option B, water, as it is the source of oxygen released during photosynthesis.
