In oxygenic photosynthesis in plants, which set of products is generated from carbon dioxide and water using light energy?

• A. Lactic acid and ethanol
• B. ATP and carbon dioxide
• C. Glucose and oxygen
• D. Nitrogen gas and water

Answer: (C)

Verified step by step guidance

1. Understand the process of oxygenic photosynthesis, which occurs in plants, algae, and cyanobacteria, where light energy is used to convert carbon dioxide and water into organic molecules and oxygen.
2. Recall the general photosynthesis equation: \$6\ \text{CO}_2 + 6\ \text{H}_2\text{O} + \text{light energy} \rightarrow \text{C}_6\text{H}_{12}\text{O}_6 + 6\ \text{O}_2$.
3. Identify the reactants: carbon dioxide (\(\text{CO}_2\)) and water (\(\text{H}_2\text{O}\)), and the products: glucose (\(\text{C}_6\text{H}_{12}\text{O}_6\)) and oxygen (\(\text{O}_2\)).
4. Note that lactic acid and ethanol are products of anaerobic respiration or fermentation, not photosynthesis.
5. Conclude that the correct set of products generated from carbon dioxide and water using light energy in oxygenic photosynthesis is glucose and oxygen.
