Solution

The correct option is C Pyruvic acid is converted into lactic acid
During exercise, the energy requirement of the body increases because of high metabolic rate. Due to the extensive physical work, shortage of oxygen (means aerobic respiration or TCA cycle cannot take place) occurs which forces the accumulated pyruvate to be converted to lactic acid and produced energy to meet the extra energy demands. So, the correct answer is option D.

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.
