Question

What substances are used up as the reactants in cellular respiration? co2 and h2o o2 and glucose o2 and h2o co2 and glucose

Answer 1

In cellular respiration, the reactants used up are oxygen and glucose, resulting in the production of energy along with carbon dioxide and water as byproducts.

Step-by-step explanation:

The substances used up as reactants in cellular respiration are oxygen (O2) and glucose (C6H12O6). During this process, oxygen is inhaled by organisms and glucose is obtained through the food they consume. These reactants are processed within the cells to release energy, with carbon dioxide (CO2) and water (H2O) as byproducts. The chemical equation representing cellular respiration is C6H12O6 + 6O2 → 6CO2 + 6H2O + Energy. This overall process is crucial for the production of adenosine triphosphate (ATP), which cells use as their main energy source.
