Question

Which of the following is a kind of anaerobic respiration?

• A. Alcoholic fermentation
• B. Lactic acid fermentation
• C. Both a and b
• D. None of the above

Answer 1

The correct option is C Both a and b

Anaerobic respiration is the process of release of energy in an enzymatically controlled stepwise incomplete (partial) degradation of organic food where $O_2$ is not being used as the terminal electron acceptor. In case of microorganisms, the term fermentation is used more often instead of anaerobic respiration. Fermentation is classified into alcoholic fermentation (where ethanol or ethyl alcohol is the end product) and lactic acid fermentation (when lactic acid is the end product).
