Absence of oxygen as in anerobic fermentations by yeast cells convert pyruvate into

Correct option is C

The correct answer is (C)  ​Ethanol+ Carbon dioxide + Energy

Information booster:

In the absence of oxygen, as in anaerobic fermentation by yeast cells, pyruvate is converted into ethanol (alcohol) and carbon dioxide. This process is known as alcoholic fermentation.

1. Pyruvate, produced from glucose during glycolysis, is decarboxylated (removal of a carbon atom) to form acetaldehyde.
2. Acetaldehyde is then reduced to ethanol (ethyl alcohol) by the enzyme alcohol dehydrogenase, with NADH being oxidized back to NAD+, which is required for glycolysis to continue.

This allows yeast cells to generate energy (in the form of ATP) in the absence of oxygen. Alcoholic fermentation is commonly used in the production of alcoholic beverages and bread.
