(i) Yeast can convert glucose into ethanol and carbon dioxide.
(ii) Fermentation takes place in aerobic bacteria only.
(iii) The site for fermentation is in cytoplasm.
(iv) Fermentation is a form of anaerobic respiration.
Choose the correct option.

• A. (i) and (iii)
• B. (ii) and (iii)
• C. (ii) and (iv)
• D. (i), (iii), and (iv)

Answer 1

The correct option is D (i), (iii), 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 in the cytoplasm, whereas cellular respiration takes place in mitochondria, which provides an aerobic environment for the complete breakdown of food.
