P4: Describe the role of energy in the body and the physiology of three named body systems in relation to energy metabolism

Energy laws

One of the laws is thermodynamics which is also known as the conservation of energy. A consequence of this law is that energy cannot be created or destroyed, it can only be transformed from one state to another. The only thing that can happen to energy in a closed system is that it can change form, for instance chemical energy can become kinetic energy. The other part of this law is transformation of energy which is the transformation of energy from one form into another. This form might not be capable of being measured or of use.

Forms of energy

Chemical energy is the most common form out of the several forms that there are of it. The chemical bond is what combines atoms or molecules with one another, energy is found within these bonds. Once a newly formed bond is produced through two atoms, energy is needed in order for this bond to be formed successfully. The energy that is used is normally heat energy, however light and electrical energy can
