Best Answer

The process of glycolysis (literally meaning splitting of sugar) occurs first at the start of cellular respiration.In this process glucose molecule breaks down into two molecules of pyruvic acid. This process takes place in cytosol for which oxygen is not essential.

  • After then following steps take place
  1. pyruvic acid oxidation
  2. Krebs cycle.

The above two reactions occur within the mitochondria.
