BIOXI14: RESPIRATION IN PLANTS
337460
In which one of the following processes \(\mathrm{CO}_{2}\) is not released?
1 Aerobic respiration in plants
2 Alcoholic fermentation
3 Aerobic respiration in animals
4 Lactate fermentation
Explanation:
Lactic acid fermentation produces lactic acid only as pyruvic acid produced in glycolysis is directly reduced by NADH to form lactic acid, without producing carbon dioxide.
