Question

What makes the concept map of fermentation in yeast complete?

• A. 1 – Starch, 2- H_2, 3- Ethanol
• B. 1 – Glucose, 2- CO_2, 3- Butanol
• C. 1 – Starch, 2- H_2, 3- Lactic acid
• D. 1 – Glucose, 2- O_2, 3- Ethyl alcohol

Answer 1

The correct option is D

1 – Glucose, 2- O_2, 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.
