The electron transport chain consists of four protein complexes that receive electrons from NADH and FADH2 and pumps out protons into the intermembrane space.

Oxidative phosphorylation is the final phase of cellular respiration. It produces 28 molecules of adenosine triphosphate (ATP).

The citric acid cycle is the second phase of cellular respiration. It creates 2 ATP as well as energy precursors used in oxidative phosphorylation.

Glycolysis refers to breaking down glucose to produce energy. It is the first phase of cellular respiration and generates byproducts that are used in other energy systems.

Anaerobic respiration refers to producing energy without the presence of oxygen. While it generates ATP rapidly, it also creates lactate as a byproduct.

Aerobic respiration refers to breaking down glucose with the presence of sufficient oxygen. It is the most efficient way to produce ATP.

The phosphagen system uses stored ATP and CP for energy during short and intense exercises. It is the fastest of the three energy production systems to produce energy.
