Question

which chemical reaction below is cellular respiration?
6o₂ + c₆h₁₂o₆ → 6co₂ + 6h₂o
6co₂ + 6o₂ → 6h₂o + c₆h₁₂o₆
6co₂ + 6h₂o → c₆h₁₂o₆ + 6o₂

Explanation:

Step1: Recall cellular respiration equation

Cellular respiration is the process of breaking down glucose ($C_6H_{12}O_6$) in the presence of oxygen ($O_2$) to produce carbon - dioxide ($CO_2$), water ($H_2O$) and energy. The balanced chemical equation is $C_6H_{12}O_6+6O_2
ightarrow6CO_2 + 6H_2O$.

Answer:

The chemical reaction $C_6H_{12}O_6+6O_2
ightarrow6CO_2 + 6H_2O$ (the first reaction shown in the image) is cellular respiration.
