ATP (Adenosine Tri-Phosphate)
The primary energy carrier in cells, used by muscles during contraction.
ATP Hydrolysis
The breakdown of ATP that releases energy when the third phosphate group is removed.
ATP Re-Synthesis
The process of regenerating ATP by adding a phosphate group back onto ADP.
ATP-PC System
An anaerobic energy system that provides a rapid supply of ATP through the breakdown of phosphocreatine.
Glycolytic System
An anaerobic energy system that re-synthesizes ATP through the breakdown of glucose.
Aerobic System
An energy system that produces ATP through the use of oxygen, typically during prolonged, lower intensity exercise.
Phosphocreatine (PC)
A molecule that helps regenerate ATP in the ATP-PC system.
Lactic Acid
A byproduct of anaerobic metabolism when pyruvate is converted due to a lack of oxygen.
Enzymatic Reactions in Glycolysis
A series of 10 chemical reactions that break down glucose to produce ATP.
NAD (Nicotinamide Adenine Dinucleotide)
A coenzyme used in cellular respiration to transfer electrons through the electron transport chain.
