Alcoholic fermentation is the type of fermentation that occurs in yeast. Anaerobic respiration, namely alcoholic fermentation.This process is very similar to glycolysis, except for the fact that alcoholic fermentation replaces one enzyme with two enzymes that change pyruvic acid into ethanol and carbon dioxide. The two main types occur in the body and in yeast   ----. Edit.

Figure 7-23Fermentation in yeast produces ethyl alcohol. The carbon dioxide that isreleased during fermentation creates bubbles and pockets that make breadrise. The alcohol evaporates during baking. There are also fungi and bacteria that produce lactic acid duringfermentation, just as your muscle cells do.Humans use these microbes totransform milk into cheese and yogurt.hen yeast cells are kept in ananaerobic environmentâan environment without oxygenâthey areforced to ferment sugar and other foods. In contrast to fermentation inyour muscle cells, fermentation in yeast produces alcohol, instead oflactic acid, as a waste product (Figure 7-23).
