Energy needed for cellular function comes from the "burning" or of glucose, fats, and protein.

Oxidation

Energy needed for cellular function comes from the "burning" or oxidation of glucose, fats, and protein.

Oxidation is a type of reaction in which there is loss of electrons during a reaction by a molecule, atom or ion. Oxidation takes place when the oxidation state of a molecule is increased and it causes the molecule to change rapidly or slowly due to of the addition of oxygen.

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy
