Which of the following is a reactant during cellular respiration? (3 points) Carbon dioxide Glucose Energy Water

## Step 1Cellular respiration is a process that cells use to produce energy from glucose and other organic molecules. This process involves three main stages: glycolysis, the Krebs cycle, and the electron transport chain.## Step 2The reactants of cellular respiration are the substances that are used up in the process to produce energy. In the case of cellular respiration, the reactants are glucose and oxygen.## Step 3Glucose is a type of sugar that is used by cells as a source of energy. Oxygen is required for the process of cellular respiration to occur.## Step 4The other options, carbon dioxide, energy, and water, are not reactants but are products of cellular respiration. Carbon dioxide is produced as a waste product, while water is produced when oxygen combines with hydrogen.
