Question
CO2 is not released in which of the following processes?
- Aerobic respiration in plants
- Aerobic respiration in animals
- Alcoholic fermentation
- Lactate fermentation
Hint:
The process in which 
is not released is a metabolic process by which glucose and many other six-carbon sugars are converted into cellular energy and a specific metabolite.
The correct answer is: Lactate fermentation
The process in which is not released is lactate fermentation.
- Lactate fermentation is an anaerobic fermentation (in the absence of oxygen) reaction that will take place in some types of bacteria and animal cells, such as in muscle cells.
- Lactate dehydrogenase catalyzes the interconversion of the respiratory substrate i.e. pyruvate into the lactate with concomitant conversion of the molecule NADH and NAD+
- And thus there is no production of .
