Net yield of H2O in Photosynthesis is__________?
Correct answer: D. 0 molecule
- A. 1 molecule
- B. 6 molecules
- C. 3 molecules
- D. 0 molecule
Explanation
The simplified photosynthesis equation can be written as 6CO2 + 6H2O -> C6H12O6 + 6O2, so water is used rather than produced and its net yield is 0 molecule. Students may choose 6 molecules by reading the water coefficient in an alternative expanded equation without cancelling the water molecules appearing on both sides.
