Identifying the byproduct of lactic acid fermentation.
Oxygen
Pyruvic acid
Lactic acid
Carbon dioxide
The byproduct of lactic acid fermentation is lactic acid.
The byproduct of lactic acid fermentation is lactic acid. To identify this, you need to understand the process of lactic acid fermentation.
Lactic acid fermentation is a metabolic process that occurs in certain microorganisms, such as bacteria and fungi, as well as in muscle cells during intense physical activity when the demand for energy exceeds the available oxygen supply.
During lactic acid fermentation, glucose is converted into two molecules of lactic acid. This process involves the breakdown of glucose into pyruvic acid, and then the conversion of pyruvic acid into lactic acid.
The other options, oxygen and carbon dioxide, are not the byproducts of lactic acid fermentation. Oxygen is not involved in this anaerobic process, and carbon dioxide is not produced during lactic acid fermentation.
Therefore, the correct answer is lactic acid.
