AP BIOLOGY

Detailed explanation-1: -In the homolactic pathway, it produces lactic acid as waste. In the heterolactic pathway, it produces lactic acid as well as ethanol and carbon dioxide.

Detailed explanation-2: -Very broadly, fermentation is a biological reaction that harvests energy from the chemical bonds in sugars. When yeast carries out fermentation, it breaks down simple sugars, and produces carbon dioxide and alcohol as waste products.

Detailed explanation-3: -There is just one waste product called lactic acid. Lactic acid is a molecule with the formula C₃H₆O₃. A molecule of lactic acid contains atoms of carbon, hydrogen and oxygen. When you run fast lactic acid builds up in the muscles, causing painful cramps.

Detailed explanation-4: -Animals and some bacteria and fungi carry out lactic acid fermentation. Lactic acid is a waste product of this process. Our muscles perform lactic acid fermentation during strenuous exercise, since oxygen cannot be delivered to the muscles quickly enough.

Detailed explanation-5: -Lactic acid is the three carbon reactant/waste product of lactic acid fermentation. It causes a burning feeling in your muscles/blood vessels during exercise.
