Aerobic glycolysis is a metabolic process that occurs in the presence of oxygen, where glucose is broken down to produce energy. This process takes place in the cytoplasm of cells and results in the production of pyruvate, which can then enter the mitochondria for further energy extraction. The primary energy currency generated during aerobic glycolysis is ATP (adenosine triphosphate), which cells use for various functions. In addition to ATP, aerobic glycolysis also produces NADH, a molecule that carries electrons to the electron transport chain in the mitochondria. This allows for the efficient production of more ATP through oxidative phosphorylation. Aerobic glycolysis is crucial for activities that require sustained energy, such as long-distance running or cycling.
