Inside the Mitochondria

The Mitochondria makes energy molecules -ATP. To do this, it goes through three processes: Glycolysis, the Kreb's (or Cirtric Acid) Cylce, and Oxadative Phosphorilation.
First, Glycolysis occurs. It happens out in the cytoplasm near the Mitochondria, and processes sugar, or glucose, to make Pyruvate. Each Glucose makes two Pyruvate. This process can be done with or without Oxygen. With Oxygen, the normal sub-products are made: ATP and NADH, which are used later in the process. However, without Oxygen the side products are either Lactic Acid or Ethanol.
Second is actually a sub-process, called Pyruvate Conversion, where a molecule of carbon dioxide is pulled off of Pyruvate, as well as more NADH, and the converted Pyruvate is sent into the Kreb's Cycle.
The Kreb's, or Citric Acid, cycle is where the last of the NADH and a FADH2 is made, and, following, ATP is made by CO2 being added and taken away from the Pyruvate.
Finally, the three NADH's and one FADH2 made by each Pyruvate going through this process go to the ETC- the Electron Transport Chain. The two molecules each carry two electrons on them that they release into the Chain to open up Proton Pumps, helping create a Proton Gradient that in the end makes the final amount of ATP.
