New molecules are produced and spent as old ones are broken down and disposed of. Our metabolism is a massive, complex, yet perfectly orchestrated system of energy that enables us to survive and thrive. In almost every chemical reaction in the body, a spark is needed to energize the reaction. This spark is provided by adenosine tri-phosphate (ATP), the energy molecule. It is fundamental to our physiology. Amazingly, the body must produce half its own weight in ATP every day. It is a wise life strategy to give ATP production all the help we can. If this system is not working well we may feel tired and fatigued and our health may be affected. Within each cell there are typically 1,000-2,000 mitochondria. This organelle is the site of three connected, complex, multi-stage biochemical processes - the Glycolytic cycle, the Krebs cycle, and the Electron Transport chain - these produce ATP.
