Given what we know about biological mechanisms in aerobic exercise, we can confirm that most of the ATP for this activity will be derived from the breakdown of fatty acids through beta-oxidation in the mitochondria of cells.
ATP is a molecule that functions as the substrate necessary for all metabolic reactions in the human body. The production of this molecule can be carried out by distinct processes. The energy for this exercise done by Bill will come from the burning and breakdown of fatty acids.
For the energy consumed during aerobic exercises, we can confirm that it is derived from the burning and breakdown of fatty acids through a process known as beta-oxidation. This is one of the many processes responsible for the production of ATP and therefore will happen within the mitochondria of a cell.
