Understand the context of fermentation: Fermentation is a metabolic process that converts sugar to acids, gases, or alcohol. It occurs in yeast and bacteria, and also in oxygen-starved muscle cells, as in the case of lactic acid fermentation.
Identify the types of fermentation: There are two main types of fermentation relevant to this problem: lactic acid fermentation and alcoholic fermentation.
Examine lactic acid fermentation: In lactic acid fermentation, glucose is converted into cellular energy and the metabolite lactate, which is lactic acid in solution.
Examine alcoholic fermentation: In alcoholic fermentation, glucose is converted into cellular energy, producing ethanol and carbon dioxide as byproducts.
Determine the common product: Both processes generate ATP as a form of cellular energy, which is a common product of both lactic acid fermentation and alcoholic fermentation.
