Introduction

Aerobic metabolism is a set of three basic metabolic processes that occur in cells to generate energy (ATP). The following are the three metabolic pathways in order:

    • Glycolysis
    • TCA cycle
    • Electron transport chain (ETC)

Glycolysis begins with the breakup of glucose and it occurs in all cells because it takes place in the cytoplasm even in the absence of oxygen. The TCA cycle and ETC is a process of cellular respiration that occurs in the mitochondria. This process occurs only in the presence of oxygen.
