To solve this problem, we need to recognize that cellular respiration is essentially the reverse process of photosynthesis. Photosynthesis converts carbon dioxide and water into glucose and oxygen, while cellular respiration breaks down glucose and oxygen into carbon dioxide and water.
Given the chemical equation for photosynthesis:
[tex]\[ 6 \text{CO}_2 + 6 \text{H}_2\text{O} \rightarrow \text{C}_6\text{H}_{12}\text{O}_6 + 6 \text{O}_2 \][/tex]
We simply reverse the products and reactants for cellular respiration:
[tex]\[ \text{C}_6\text{H}_{12}\text{O}_6 + 6 \text{O}_2 \rightarrow 6 \text{CO}_2 + 6 \text{H}_2\text{O} \][/tex]
So, the correct answer is:
C. [tex]\[ \text{C}_6\text{H}_{12}\text{O}_6 + 6 \text{O}_2 \rightarrow 6 \text{CO}_2 + 6 \text{H}_2\text{O} \][/tex]
