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? water, oxygen, carbon dioxide, glucose

Explanation:

In a chemical equation, reactants are on the left - hand side of the arrow. The equation for photosynthesis is "carbon dioxide + water → glucose + oxygen". So, we look for the substances on the left - hand side.

Answer:

water, carbon dioxide
