To solve the question of how many glucose molecules can be formed by 6 molecules of carbon dioxide (CO₂), we need to refer to the chemical equation for photosynthesis, which is:
[tex]\[ 6 \text{CO}_2 + 6 \text{H}_2O \rightarrow \text{C}_6\text{H}_{12}\text{O}_6 + 6 \text{O}_2 \][/tex]
This equation tells us that 6 molecules of carbon dioxide (CO₂) react with 6 molecules of water (H₂O) to form 1 molecule of glucose (C₆H₁₂O₆) and 6 molecules of oxygen (O₂).
Given that we have 6 molecules of carbon dioxide, we can observe from the equation that this exact amount of carbon dioxide will produce:
[tex]\[ \frac{6 \text{ CO}_2}{6} = 1 \text{ molecule of glucose (C}_6\text{H}_{12}\text{O}_6\text{)} \][/tex]
So, based on the balanced chemical equation for photosynthesis, 6 molecules of carbon dioxide will form exactly 1 molecule of glucose.
Therefore, the correct answer is:
C. 1
