In the mitochondrion, small molecules combine with oxygen to produce water and carbon-di-oxide. This process releases a large amount of energy.

Explanation:

The mitochondrial membrane is where the chemical processes happen, and where the fluid contains the matrix. It form an integral part of eukaryotic cells. Its principal function is to conduct cellular respiration. This implies that the cell sucks in nutrients, breaks it down and transforms it into energy.The oxygen present inside the cell is applied and mitochondria transform chemical energy from food in the cell into energy in a form that is accessible to the host cell, understood as oxidative phosphorylation, it occurs within mitochondria. The processes identified as the citric acid or Krebs cycle generate a chemical called NADH in the mitochondria matrix. NADH is then used to produce adenosine triphosphate (ATP) through enzymes located in the inner cone of the mitochondrial membrane. Within ATP the energy is contained within chemical bonds form. You can open those bonds and retrieve the energy.

Moles = mass/molar mass the molar mass of c20 = 12.011*20 = 240.22 g per mole therefore, the number of moles is 20 g / 240.22 g per mol = 0.0833 moles.
