Detailed explanation-1: -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.

Detailed explanation-2: -In organisms that perform cellular respiration, glycolysis is the first stage of this process. However, glycolysis doesn’t require oxygen, and many anaerobic organisms-organisms that do not use oxygen-also have this pathway.

Detailed explanation-3: -Glycolysis (see “Glycolysis” concept) is an anaerobic process-it does not need oxygen to proceed. This process produces a minimal amount of ATP. The Krebs cycle and electron transport do need oxygen to proceed, and in the presence of oxygen, these process produce much more ATP than glycolysis alone.

Detailed explanation-4: -Glycolysis is unique in that it takes place within the cytoplasm of the cell and does not require oxygen. It is an anaerobic reaction that produces pyruvate, NAD, and ATP. Know the products and reactants of glycolysis.

Detailed explanation-5: -Glycolysis is the partial oxidation of glucose to produce pyruvate, which is then transferred to mitochondria for further oxidation. The cytosol is the fluid in which the cell’s organelles are located. No, glycolysis does not takes place in the mitochondria. It occurs in the cytosol.
