Question

In which one of the following processes $C{O}_2$ is not released?

• A. Aerobic respiration in plants
• B. Aerobic respiration in animals
• C. Alcoholic fermentation
• D. Lactate fermentation

Answer 1

Answer: (D)

Lactate fermentation

Aerobic respiration in plants and animals oxidizes the respiratory substrate and produces carbon dioxide and water along with ATP.

Anaerobic respiration is a type of respiration which takes place in the absence of oxygen. it is also known as fermentation.

Alcoholic fermentation is a type of anaerobic respiration in which the respiratory substrate is converted to carbon dioxide and alcohol along with the production of ATP.

Lactate fermentation is a type of anaerobic respiration in which the respiratory substrate is converted into lactate along with the production of ATP. It takes place in muscles during strenuous physical work.

So, the correct answer is 'Lactate fermentation'.
