Question

sometimes there is not enough oxygen in a cell for cellular respiration to occur. in this case, the cell may use the process of fermentation to get the energy it needs in order to carry out cellular processes. fermentation is the breakdown of organic compounds in the absence of oxygen. the byproducts of fermentation differ from cellular respiration. which of the following is a chemical byproduct of fermentation in humans? (1 point) adp pyruvate lactic acid glucose

Explanation:

In human cells, when oxygen is scarce and fermentation occurs, lactic - acid fermentation takes place. Glucose is first broken down to pyruvate, and then pyruvate is converted to lactic acid. ADP is involved in energy - transfer processes but is not a byproduct of fermentation. Pyruvate is an intermediate in the process, not the final byproduct. Glucose is the starting molecule for fermentation, not a byproduct.

Answer:

C. lactic acid
