Lactic acid fermentation happens in bacteria, fungi, and animal cells. It is a pretty simple follow-up to glycolysis: the pyruvate molecules are reduced to lactate, while NADH is oxidized to NAD + . In this way, NAD + is replenished for glycolysis. Lactic acid fermentation happens in some fungi and bacteria, but also in animal muscle cells.

There are two types of cell respiration: aerobic cell respiration, a reaction with the participation of molecular oxygen (O₂); and anaerobic cell respiration, without the participation of molecular oxygen and which uses other inorganic molecules as an oxidant instead.

This is a process that stores energy in the produced ATP molecule. When ATP provides energy to the cellular metabolism, it releases one of its phosphate ions and ADP reappears. ADP can also release more phosphate ions and generate AMP (adenosine monophosphate) or even non-phosphorylated adenosine.

Yeast fermentation is used to make wine and beer as well as bake bread. This process relies on a similar principal as lactic acid fermentation. Under anaerobic conditions, these cells can't go through the citric acid cycle and electron transport chain.

Without oxygen, these cells only undergo glycolysis and produce 2 ATP per glucose molecule. Next, they need to reduce pyruvate to regenerate NAD+ from NADH + H+. Fermentation is the process that performs this job. In lactic acid fermentation, pyruvate is reduced to lactic acid. This occurs in cells such as our muscles when we're exercising. In alcoholic fermentation, pyruvate is reduced to alcohol and releases carbon dioxide.

When in an anaerobic environment, some cells can use glycolysis and fermentation to keep producing ATP. Lactic acid fermentation happens in our muscle cells when we are exercising feverishly, while alcoholic fermentation is used in yeast cells and is what leads to beer, bread, and wine.

Therefore, in anaerobic conditions, some organisms perform fermentation, which is a process that anaerobically generates ATP by performing glycolysis and one extra step. There are two types of fermentation we'll discuss in this lesson-lactic acid fermentation and alcoholic fermentation.

After aerobic respiration, 38 ATP molecules are produced from the consumption of one glucose molecule (but two of these ATP molecules are consumed by glycolysis). The net gain of the process is then 36 ATP molecules per glucose molecule.

4. Some cells that usually obtain energy from aerobic cellular respiration can use fermentation when oxygen is not available. There are bacteria and fungi that, in the absence of oxygen, use their anaerobic metabolic capability for energy supply. Muscle cells also use fermentation when oxygen is scarce.

Alcohol fermentation is pretty similar to lactic acid fermentation. Instead of the pyruvate being reduced to lactate, it is reduced to ethanol, and lets off two molecules of CO 2 along the way. Two kinds of organisms use alcohol fermentation: bacteria and yeast (yeast are fungi, btw). Humans use alcohol fermentation in another way, by using it to make bread, beer and wine. We'll talk more about that in another section.

what types of organisms go through fermentation?
A muscle is a type of organism that goes through fermentation. Our muscles go through fermentation.
