Question

which equation represents cellular respiration; c₆h₁₂o₆ -> 2c₂h₅oh + 2co₂; c₆h₁₂o₆ + 6o₂ 6co₂ + 6h₂o; 6 co₂ + 6 h₂o sun c₆h₁₂o₆ + 6 o₂; a² + b² = c²

Explanation:

Cellular respiration is the process where glucose ($\text{C}_6\text{H}_{12}\text{O}_6$) reacts with oxygen ($\text{O}_2$) to produce carbon dioxide ($\text{CO}_2$), water ($\text{H}_2\text{O}$), and energy. The second equation matches this reaction. The first is fermentation, the third is photosynthesis, and the fourth is the Pythagorean theorem (unrelated).

Answer:

$\text{C}_6\text{H}_{12}\text{O}_6 + 6\text{O}_2
ightarrow 6\text{CO}_2 + 6\text{H}_2\text{O}$
