How Do You Measure Energy In Regards to Nutrition? Energy is the capacity or potential to perform work. Work is one form of energy, known as mechanical energy. Work is performed from the hydrolysis (breakdown) of something called adenosine triphosphate (ATP). ATP is the energy currency in the body and powers all forms of mechanical […]

Since there is not enough available oxygen, the pyruvate produced by glycolysis cannot be oxidized. Furthermore, since energy production must continue, ATP production from glycolysis must increase.
