Question

a) 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.
a) cellular respiration can be summarized by this chemical equation:
a) glucose + oxygen → carbon dioxide + water
a) 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.
a) which of the following are key reactants of cellular respiration? select two.
a) checked water checked glucose
checked oxygen checked carbon dioxide

Explanation:

Cellular respiration's key reactants are the substances that start the reaction. The provided text states the process uses glucose and oxygen to produce carbon dioxide and water, so glucose and oxygen are the starting reactants.

Answer:

B. glucose
C. oxygen
