1 Angiotensin, which is involved in blood pressure control. 2  Adiponectin, which improves the bodyâs sensitivity to insulin and so helps to protect against developing type 2 diabetes.  Lipoprotein lipase and apolipoprotein E, which are involved in storage and metabolism of fat to release energy.
Energy system can refer to: 1  Electric power system, for supply, transmission and consumption of electric power. 2  Thermodynamic system, a physics concept for analysis of thermal energy exchange.  Bioenergetic systems, metabolic processes for converting energy in living organisms.
Internal energy is the sum of all microscopic forms of energy of a system. It is the energy needed to create the system. It is related to the potential energy, e.g., molecular structure, crystal structure, and other geometric aspects, as well as the motion of the particles, in form of kinetic energy.
