Which of the following statement(s) is (are) correct?
(i) Pyruvate can be converted into ethanol and carbon dioxide by yeast.
(ii) Fermentation takes place in aerobic bacteria.
(iii) Fermentation takes place in mitochondria.
(iv) Fermentation is a form of anaerobic respiration.
(i) and (iii)
(ii) and (iv)
(i) and (iv)
(ii) and (iii)
(i) and (iv)
The correct option is C.
Explanation of correct option:
Statement (i):
Statement (iv):
Explanation of incorrect options:
Statement (ii):
Fermentation happens in facultative anaerobes like yeast, in some bacteria and fungi that must exist in an oxygen-free environment to survive (known as obligatory anaerobes), and in muscle cells when oxygen is scarce.
Statement (iii):
Aerobic respiration takes place in mitochondria, while fermentation occurs in the cytoplasm of bacteria that respire anaerobically.
Final answer: The correct statements are Pyruvate can be converted into ethanol and carbon dioxide by yeast and Fermentation is a form of anaerobic respiration. Hence, Option C is correct.
