Solution

The correct option is D (i) and (iv)
Yeast is a fungus that can utilise its enzymes in an anaerobic environment to convert glucose into ethanol and carbon dioxide. The site for fermentation is the cytoplasm, whereas cellular respiration takes place in the mitochondria, which provides an aerobic environment for the complete breakdown of food.

Q. Which of the following statement are correct?
A. Pyruvate can be converted into ethanol and carbon dioxide by yeast.
B. Fermentation takes place in aerobic bacteria.
C. Fermentation takes place in mitochondria
D. Fermentation is a kind of anaerobic respiration.

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.
