Document Summary
Ability to do so determines exercise capacity. Chemical or electrical work (ex: cell function) Note: we need energy for many other forms of biological work (not just exercise) Sum of all chemical reactions in the body. The metabolic process of converting food stu s into biologically useable energy (atp) Study of energy transfer via chemical reactions in living tissues. Flow/exchange of energy within a living system. As we go through metabolism, you will see how this works in the human body in response to exercise or physical activity. Energy cannot be created or destroyed only transferred from one form to another. Body does not produce, consume or use up energy: instead it transforms it from one state to another as physiologic systems undergo continual change. E ciency = work produced / free energy of atp. At rest all metabolic processes produce heat. Energy needed to increase 1kg of water 1 degrees celceus.
