Answer 1

The complete oxidation of glucose involves four phases.1. Glycolysis, the splitting of glucose into two 3-carbon molecules

 

2. The preparatory reaction, which divides each 3-carbon molecule into a 2-carbon molecule and CO23. The citric acid or Krebs cycle, which produces CO2, NADH, FADH2, and ATP

 

4. The electron transport chain also known as the electron transport system, assists in the production of the largest amount of ATP
