What is the main carbohydrate produced during photosynthesis?

• A. Oxygen
• B. Nitrogen
• C. Water
• D. Glucose

Answer: (D)

During photosynthesis, the energy from light is used to convert carbon dioxide and water into organic molecules that the plant can use or store. The main carbohydrate produced is glucose, because the Calvin cycle builds sugar units from carbon dioxide and then assembles them into glucose, the simple sugar that serves as a key building block for larger carbohydrates like starch and sucrose. The oxygen you often see released comes from splitting water, not from forming a carbohydrate. Nitrogen isn’t produced in this process, and water is a reactant used in the reactions. So the primary carbohydrate formed is glucose.
