Which compounds are reactants in the process of cellular respiration? h2o and o2 h2o and co2 c6h12o6and o2 c6h12o6 and co2

The reactants are C₆H₁₂O₆ and O₂.

Cellular respiration involves the oxidation of glucose (C₆H₁₂O₆) to CO₂ and H₂O.

The equation for the reaction is

C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O

Thus, the reactants are C₆H₁₂O₆ and O₂.

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.
