The Oxygen molecule determines if the Pyruvic acid enters Krebs cycle or undergoes fermentation. If Oxygen is present, it enters the Krebs cycle, whereas in its absence, it undergoes fermentation.
Oxygen is the most likely answer.
Cells with perform cellular respiration (those that are capable of doing such) in the presence of oxygen because it yields a higher amount of ATP per 1 molecule of glucose. In the absence of oxygen, cells, at least animal cells i.e. muscle cells, will perform glycolysis, which yields less ATP per molecule of glucose. Fermentation is performed by both prokaryotic and eukaryotic cells, but the best example is yeast which produces ethanol from glucose in the absence of oxygen.
glycolysis occurs in the cytoplasm and the product of glycolysis moves into the mitochondria for cellular respiration. Red blood cells use glycolysis exclusively as they do not have mitochondria. Basically fermentation takes place in the absence of oxygen.
Pyruvate is changed into lactic acid in animal fermentation. In the fermentation of plants, pyruvate is changed into alcohol and carbon dioxide.
It just happens!

Cellular respiration and fermentation are two different processes.
Fermentation: Takes place without oxygen, takes place in cytoplasm. Cellular respiration: Requires oxygen, takes place in cytoplasm and mitochondria. Both: Are ways that organisms produce energy by breaking down glucose.
like respiration, fermentation begins in the cytoplasm. Again, as the glucose molecules are broken down, energy is released. But the simple molecules from the break down of glu- cose do not move into the mitochondria!!!
At the completion of the glycolic process, pyruvic acid is produced. Some of the pyruvic acid ends up in the cell mitochondria where cellular respiration takes place. In the absence of oxygen, the pyruvic acid goes through a process of fermentation, which takes place in the cytoplasm of the cell.
Mitochondrion
for cellular respiration a process of oxidation takes place at some stage (aerobic) while in fermentation it is in abscence of oxygen(anaerobic)
No, it is required only in cellular respiration. Fermentation takes place in the absence of oxygen.
Cellular respiration and fermentation are two different processes.
Correct. Anaerobic cellular respiration takes place in the cytoplasm and gives a net yield of 2 ATP molecules. Anaerobic respiration consists of glycolysis followed by either lactic acid fermentation or alcoholic fermentation.

actually there are two types of cellular respiration:aerobic and anaerobic. aerobic cellular respiration only takes place when there is a presence of oxygen, while anaerobic or also called as fermentation takes place even w/out oxygen.

Anaerobic respiration? Glycogen is utilised into glucose plus 6 atoms of phosphate which creates lactic acid (2 ATP). If that is what you were asking.
cellular respiration if there is enough oxygen. Lactic Acid fermentation if there is a lack of oxygen.
Mitochondrion
At the completion of the glycolic process, pyruvic acid is produced. Some of the pyruvic acid ends up in the cell mitochondria where cellular respiration takes place. In the absence of oxygen, the pyruvic acid goes through a process of fermentation, which takes place in the cytoplasm of the cell.
