NEETBiologyRespiration in PlantsMCQ+4 / −1
In which one of the following processes CO2 is not released?
  1. A
    Aerobic respiration in plants
  2. B
    Areobic respiration in animals
  3. C
    Alcoholic fermentation
  4. D
    Lactic fermentation
View written solutionFree

Correct answer: D

Lactic acid fermentation : It occurs in lactic acid bacteria (Lactobacillus) and muscles (Human). Pyruvic acid produced in glycolysis is reduced by NADH2 to form lactic acid without producing carbon dioxide.
