Answer:
The correct answer is - option D. fermentation.
Explanation:
Glycolysis is the metabolic pathway in which metabolize the sugar and produce pyruvate molecule or lactic acid and produce the energy in the form of ATP and NADH.
Glycolysis is an example of the fermentation as fermentation is also a metabolic pathway in which an organism turns glucose into the lactic acid or the alcohol to produce energy for electron transfer system.
Thus, the correct answer is - option D. fermentation.
CO2 = Carbon + two Oxygen
Glucose= C6H12O6 = six Carbon + twelve Hydrogen + six Oxygen
so the answer is Carbon and Oxygen.
