Question

Find out A, B, C, and D products of anaerobic respiration pathway cited below \includegraphics[width=0.4\linewidth]{5image.png}

• A. \( \text{A- Glucose, B- Pyruvic acid, C- Ethanol, D- Sucrose} \)
• B. \( \text{A- Glucose, B- Pyruvic acid, C- Ethanol, D- Lactic acid} \)
• C. \( \text{A- Glucose, B- Pyruvic acid, C- Lactic acid, D- Ethanol} \)
• D. \( \text{A- Glucose, B- Lactose, C- Ethanol, D- Pyruvic acid} \)

Hint:

In anaerobic conditions, glucose is converted into pyruvic acid which can then be further converted into ethanol (alcoholic fermentation) or lactic acid (lactic acid fermentation), depending on the conditions.

Answer 1

The Correct Option is B

Step 1: In the anaerobic respiration pathway, glucose is first converted into pyruvic acid. Then, depending on the pathway, pyruvic acid may undergo fermentation to form ethanol or lactic acid. Therefore,
- A = Glucose (starting molecule of anaerobic respiration).
- B = Pyruvic acid (intermediate product).
- C = Ethanol or Lactic acid (products of fermentation).
- D = Lactic acid (when fermentation leads to lactic acid).
