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

The correct option is D Lactate fermentation

Lactic acid fermentation or Lactate fermentation is the only process during which carbon dioxide is not released.
During this proces, which is a type of anaerobic respiration, glucose is converted into lactic acid with the release of 2 ATP and is commonly seen in bacteria such as lactobacilli and muscle cells of animals.

Carbon dioxide is release during aerobic respiration in plants and animals as well as during alcoholic fermentation, which is the other type of anaerobic respiration.
