Question

cellular respiration 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.
cellular respiration can be summarized by this chemical equation:
glucose + oxygen → carbon dioxide + water
glucose, like other sugar molecules, often serves as an energy source for cells. cells release energy by breaking down glucose through chemical reactions with oxygen gas. this process produces carbon dioxide gas and water.
which of the following are key reactants of cellular respiration?
carbon dioxide
water
glucose
oxygen

Explanation:

In a chemical equation, reactants are on the left side of the arrow. The equation for cellular respiration is glucose + oxygen → carbon dioxide + water. So, glucose and oxygen are reactants.

Answer:

glucose, oxygen
