Question

What two compounds are the waste products of cellular respiration? * H2O and CO2 H2O and C6H12O6 CO2 and C6H12O6 ATP and CO2

Answer 1

Answer:

The two compounds that correspond to waste products of cellular respiration are H₂O and CO₂.

Explanation:

The cellular metabolic waste products, specifically from cellular respiration are water (H₂O) and carbon dioxide (CO₂), from the oxidation of glucose into energy.

The process of cellular respiration occurs in the mitochondria of eukaryotic cells and consists of a series of chemical reactions where, from a glucose molecule, energy is obtained in the form of ATP molecules.

Obtaining H₂O and CO₂ from glucose can be summarized with the schematic reaction:

                                 C₆H₁₂O₆  +  6O₂ →  6H₂O  +  6CO₂

This summary indicates that a glucose molecule, when oxidized, produces as waste 6 molecules of water and 6 molecules of carbon dioxide. To reach this process all the reactions of the oxidative phosphorylation occur and 24 molecules of ATP are obtained for each molecule of glucose.

For the other options it is important to mention that:

• C₆H₁₂O₆ is the substrate from which cellular respiration takes place.
• ATP is the final product of cellular respiration, translated into energy to be used by the cell.
