Question

How many water and carbon dioxide molecules take part, respectively, in the process of photosynthesis as indicated by the following unbalanced equation? H2O(l) + CO2(g) → C6H12O6(aq) + O2(g) = H2O(l) (In the presence of sunlight and chlorophyll).

• A. 3 and 6
• B. 6 and 6
• C. 4 and 5
• D. 6 and 3

Answer 1

Answer:

B. 6 and 6

The balanced equation for photosynthesis is: 6 H2O(l) + 6 CO2(g) → C6H12O6(aq) + 6 O2(g) Therefore, 6 molecules of water and 6 molecules of carbon dioxide are required forphotosynthesis to produce one molecule of glucose and six molecules of oxygen.
