Question 30

Photosynthesis and Plant Nutrition

Which of the following equations is not associated with photosynthesis?

  1. A.H2O → H + OH
  2. B.C6H12O6 → 2C2H5OH + 2CO2
  3. C.CO2 + [4H] → CH2O + H2O
  4. D.4[OH] → 2H2O + O2
  5. E.6CO2 + 6H2O → C6H12O6 + 6O2
Show the answer and explanation

Answer: B (C6H12O6 → 2C2H5OH + 2CO2)

Explanation

Breaking glucose into ethanol and carbon dioxide is fermentation (anaerobic respiration), not photosynthesis.
