Fermentation......
It is said to be anaerobic, which means "without oxygen". The opposite of "anaerobic" is "aerobic" which means requiring oxygen.
Anaerobic respiration takes place in the Cytoplasma.
Defining Glycolysis as ' the anaerobic degradation of glucose to yield lactic acid ', the most common location of this activity is in oxygen depleted muscle cells.
Glycolysis takes place outside of the mitochondrion
Glycolysis takes place In the cytosol. Krebs cycle and electon transport takes place Inside an intracellular inclusion known as a mitochondria.
Glycolysis does not happen in the mitochondria. It takes place in the cytoplasm. Therefore those organisms (prokaryotes) are also capable of glycolysis that do not actually have mitochondria. In the biological oxidation of glucose, glycolysis is the first step of three, and the only one that is possible without mitochondria. The last two steps, that is the citric acid cycle (Krebs-cycle) and terminal oxidation occur in the mitochondria.
Glycolysis takes place in the cytosol of the cell.
The first stage of cellular respiration is called glycolysis. It takes place in the cytoplasm of the cell and needs no oxygen.
In organisms that undergo anaerobic respiration, glycolysis occurs, which does not require oxygen. After glycolysis, fermentation takes place to regenerate NAD+ for glycolysis to continue in the absence of oxygen. The citric acid cycle and oxidative phosphorylation, which require oxygen, do not occur in anaerobic respiration.
Both of the reactions are under anaerobic conditions (the absence of oxygen is required in both cases). In the presence of oxygen, glycolysis takes place.
Glycolysis is the stage of cellular respiration where glucose is broken down into two molecules of pyruvic acid. It takes place in the cytoplasm of the cell and does not require oxygen.
Glycolysis, the breakdown of glucose into two molecules of pyruvic acid, takes place in the cytosol, outside the mitochondria
