The complex is called Acetyl Co-A. In this process one NADH molecule is produced. Electron Transport Chain – the high energy electrons trapped in NADH and FADH in glycolysis, pyruvate oxidation, and the Krebs cycle are used to produce ATP through chemiosmosis. O2 is the final acceptor of high energy electrons.
In this manner, is oxygen required for glycolysis to occur?
Glycolysis occurs in the cytosol of the cell and does not require oxygen, whereas the Krebs cycle and electron transport occur in the mitochondria and do require oxygen. Cellular respiration takes place in the stages shown here. The process begins with a molecule of glucose, which has six carbon atoms.
Why can glycolysis proceed without oxygen?
Glycolysis can occur with or without oxygen. Without oxygen, glycolysis allows cells to make small amounts of ATP. This process is called anaerobic respiration or fermentation. Fermentation also produces lactic acid, which can build up in muscle tissue causing soreness and a burning sensation.
