In oxygenic photosynthesis in plants, which molecules are the primary reactant inputs used to produce sugars and oxygen?

• A. Chlorophyll and glucose ($C_6{H}_{12}{O}_6$)
• B. ATP and NADPH
• C. Carbon dioxide ($C_1{O}_2$) and water ($H_{2}O$)
• D. Glucose ($C_6{H}_{12}{O}_6$) and oxygen ($O_2$)

Answer: (C)

Verified step by step guidance

1. Identify the overall chemical equation for oxygenic photosynthesis, which summarizes the reactants and products involved in the process.
2. Recognize that the primary reactants are carbon dioxide (CO\_2) and water (H\_2O), which plants use to produce sugars and oxygen.
3. Understand that chlorophyll is a pigment that captures light energy but is not a reactant; ATP and NADPH are energy carriers produced during the light-dependent reactions, not the initial reactants.
4. Recall that glucose (C\_6H\_12O\_6) and oxygen (O\_2) are the products formed from the reactants through the photosynthetic process.
5. Summarize that the correct primary reactant inputs for producing sugars and oxygen in oxygenic photosynthesis are carbon dioxide and water.
