Solution

The correct option is D

1 – Glucose, 2- O2, 3- Ethyl alcohol


During Fermentation, Yeast acts on its substrate (Glucose- 6 carbon compound) and converts it into ethanol and carbon dioxide in the absence of oxygen. Glucose is first converted into a 3-carbon compound, Pyruvate before it is converted to end products. This mode of respiration is called anaerobic respiration.
