Question

c₆h₁₂o₆ + 6o₂ → 6co₂ + 6h₂o
which molecules are produced in addition to
6 carbon dioxide molecules during cellular
respiration?
6 glucose molecules
6 pyruvate molecules
6 water molecules
6 oxygen molecules

Explanation:

The given chemical equation for cellular respiration is \( \ce{C6H12O6 + 6O2 -> 6CO2 + 6H2O} \). The reactants are glucose (\( \ce{C6H12O6} \)) and oxygen (\( \ce{O2} \)), and the products are carbon dioxide (\( \ce{CO2} \)) and water (\( \ce{H2O} \)). The question asks for the molecules produced in addition to 6 carbon dioxide molecules. From the equation, we can see that along with 6 \( \ce{CO2} \) molecules, 6 \( \ce{H2O} \) (water) molecules are also produced. Glucose is a reactant, pyruvate is an intermediate in cellular respiration (not a product of this overall equation), and oxygen is a reactant, so they are not the correct answers.

Answer:

6 water molecules
