Glycolysis occurs in cytosol and converts glucose to two pyruvic acid molecules.
Glycolysis produces two ATP and two NADH
The NADH can go to the electron transport chain in the inner mitochondrial membrane.
The two pyruvic acid molecules produced in glycolysis are converted to two acetyl-CoA molecules.
The conversion of pyruvic acid to those molecules produces two carbon dioxide molecules and two NADH that can go to the electron-transport chain.
The two acetyl-CoA molecules enter the citric acid cycle.
The citric acid cycle produces four carbon dioxide, six NADH, two FADH2, and two ATP.
The electron transport chain uses NADH and FADH2 to produce ATP.
The electron transport chain produces thirty two ATP.
The ATP production process in the electron transport chain requires oxygen which combines with hydrogen ions to form water.
The electron transport chain is a series of electron carriers in the inner mitochondrial membrane.
NADH and FADH2 transfer electrons to the electron transport carriers and release H+
Oxidized NAD+ and FAD are reused to transport additional electrons from the citric acid cycle.
The released electrons pass from one electron carrier to the next through a series of oxidation reduction reactions.
Three of the electron carriers also function as proton pumps which move H+ from the inner mitochondrial compartment to the outer compartment.
Each proton pump accepts one electron and uses some of its energy to export H+
The last electron carrier in the series collects the electrons and combines them with oxygen and H+ to form water.
Without oxygen to accept the electrons, the reactions of the electron transport chain cease effectively stopping aerobic respiration.
The H+ released from NADH and FADH2 are moved from the inner mitochondrial compartment to the outer mitochondrial compartment by active transport.
The concentration of H+ in the outer compartment exceeds that of the inner compartment and H+ move back into the inner compartment by diffusion.
The H+ pass through certain channels formed by the enzyme ATP synthase.
Through Chemiosmosis ATP is produced by the movement of H+ ions moving down their concentration gradient.
