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. Lactic acid fermentation

Answer 1

The correct option is D Lactic acid fermentation

Lactic acid fermentation is a process by which glucose, fructose and sucrose are converted into energy and the metabolite lactic acid. It is an anaerobic fermentation reaction that occurs in some bacteria and animal cells and allows glycolysis to continue by ensuring that NADH is returned to its oxidised state (NAD+) without releasing CO${}_2$.
