Answer :
Final answer:
In photosynthesis, water is the molecule that is converted into oxygen. This occurs during the light-dependent reactions, where water is split to release oxygen as a byproduct. Thus, the correct answer is water.
Explanation:
Photosynthesis and Oxygen Production
During the process of photosynthesis, plants convert light energy into chemical energy by using sunlight, carbon dioxide, and water as reactants. The molecule that is specifically converted into oxygen is water. When water (H2O) is split during the light-dependent reactions, it releases oxygen as a byproduct. Therefore, the correct answer to the question is:
- Water
This reaction underscores the importance of water in sustaining life on Earth, as it not only provides necessary electrons for photosynthesis but also contributes to the oxygen needed by aerobic organisms.
