Fermentation
fermentation the process where cells obtain energy from glucose without oxygen; there are two types:
lactic acid fermentation Lactic acid fermentation occurs in muscle cells after strenuous activity. Muscle cells use up oxygen faster than it can be replaced. In order to obtain energy (cellular respiration requires oxygen), the cells conduct lactic acid fermentation instead of cellular respiration.
lactic acid fermentation occurs in muscle cells after strenuous activity; the waste products are lactic acid and carbon dioxide
alcoholic fermentation Alcoholic fermentation occurs in yeast and some other unicellular organisms that break down sugars. Alcohol is produced in the process.

Why do cells need to move things in and out of them? Cells need nutrients, and they need to remove wastes. 2. Do animal cells go through a. cellular respiration? b.Photosynthesis? a. Yes b. NO
