Question

During fermentation, pyruvate is converted into carbon dioxide and G. In our muscle cells during vigorous exercise pyruvate is converted into H. In mitochondria, it is converted into carbon-dioxide and I. The fermentation process in yeast is also called J while that in mitochondria is referred to as K.


Identify G,H,I,J and K.

• A. lactic acid, water, ethanol, fermentation, break-down of glucose
• B. ethanol, lactic acid, water, anaerobic respiration, aerobic respiration
• C. water, ethanol, lactic acid, aerobic respiration, anaerobic respiration
• D. None of the above

Answer 1

The correct option is B

ethanol, lactic acid, water, anaerobic respiration, aerobic respiration

The breakdown of glucose to pyruvate occurs in the cytoplasm. In yeasts, pyruvate usually undergoes anaerobic respiration to form ethanol and carbon dioxide. This process is called fermentation. Anaerobic respiration in muscle cells produces lactic acid. In mitochodria, aerobic respiration of pyruvate produces carbon dioxide and water.
