The document discusses energy systems and ATP. It defines energy and explains that ATP provides energy for muscular contractions, circulation, nerve impulses, digestion, and tissue repair. ATP is produced through three phosphate bonds and broken down to ADP and a phosphate group, releasing energy. The three main energy systems are phosphocreatine, lactic acid, and aerobic systems, which create ATP through different pathways to power movement and bodily functions.

- 2. What is energy? • Energy is a property of objects which can be transferred to other objects or converted into different forms (Wikipedia, 2016) • The "ability of a system to perform work" is a common description, but it is misleading because energy is not necessarily available to do work (Wikipedia, 2016) • Energy gives us the capacity to do stuff (Steve, 2016 – please do not reference)
