What process converts light energy into chemical energy in plants using carbon dioxide and water?

• A. Photosynthesis
• B. Aerobic
• C. Substrate
• D. Optimum

Answer: (A)

Photosynthesis is the process by which plants capture light energy and store it as chemical energy in sugars. Chlorophyll in chloroplasts absorbs light and powers the light-dependent reactions to make ATP and NADPH, which then drive the Calvin cycle to fix carbon dioxide into glucose. Water is split in the light reactions to provide electrons and release oxygen as a by-product. In short, light energy is transformed into chemical energy stored in carbohydrate bonds, using carbon dioxide and water. Overall, 6 CO2 + 6 H2O + light energy → C6H12O6 + 6 O2. This isn’t aerobic respiration, nor a substrate or an arbitrary “optimum” term; it specifically describes how light energy becomes chemical energy in plants.
