Question

photosynthesis involves many chemical reactions. when a chemical process involves a series of reactions, scientists may summarize the process with a single chemical equation that shows only the key reactants and products. photosynthesis can be summarized by this chemical equation: carbon dioxide + water → glucose + oxygen. during photosynthesis, the atoms in water and carbon dioxide are rearranged to form energy - rich sugar molecules, like glucose, and oxygen. which of the following are key reactants of photosynthesis? glucose oxygen water carbon dioxide

Explanation:

The text states that the chemical equation for photosynthesis is carbon dioxide + water → glucose + oxygen. Reactants are substances that participate in a chemical - reaction and are on the left - hand side of the equation. So, water and carbon dioxide are reactants.

Answer:

C. water, D. carbon dioxide
