Question

Which of the following statements are correct ?
(i) pyruvate can be converted into ethanol and carbon dioxide by yeast
(ii) fermentation takes place in the case of aerobic bacteria
(iii) fermentation takes place in mitochondria
(iv) fermentation is a form of anaerobic respiration

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

Answer 1

The correct option is A (i) and (iv)

Correct answer: (c) (i) and (iv)

Pyruvate can be converted into ethanol $\left(C_2{H}_{5}OH\right)$ and carbon dioxide $\left(C{O}_2\right)$ by yeast during anaerobic respiration, releasing energy in the form of ATP. Fermentation is an anaerobic process in which some amount of energy is released from glucose in the absence of oxygen.
