Three major pathways in this process:◦ Glycolysis◦ Krebs cycle
also known as the Citric Acid Cycle◦ Oxidative Electron Transport
Oxidative Electron Transport◦ located in inner membrane
Krebs cycle ◦ located in mitochondrial matrix
(thick liquid inside inner membrane)
Matrix
Oxidative Electron Transport In the Inner Membrane
Main function ◦ to break down Glucose and produce pyruvate
Takes place outside the mitochondria ◦ in the cytoplasm of the cell
Makes 2 ATP molecules Pyruvate enters mitochondria and modified
◦ Into Acetyl CoA for next step

Main function ◦ break down Acetyl CoA to CO2
◦ produce NADH and FADH2
Carriers of high energy electrons Located in the mitochondrial matrix Makes 2 ATP molecules The CO2 you exhale is made in this pathway

Main Function◦ Accepts energized electrons from NADH and FADH2
◦ Passes those electrons to O2
◦ O2 is ultimate electron acceptor producing H20
Located within inner membrane of mitochondria Electron flow provides energy
◦ for ATP production
