The Krebs Cycle (=The Citric Acid Cycle)
This 2-carbon fragment is donated to a molecule of oxaloacetic acid.
The resulting molecule of citric acid (which gives its name to the process) undergoes the series of enzymatic steps shown in the diagram.
The final step regenerates a molecule of oxaloacetic acid and the cycle is ready to turn again.
Summary:
Each of the 3 carbon atoms present in the pyruvate that entered the mitochondrion leaves as a molecule of carbon dioxide (CO2).
At 4 steps, a pair of electrons (2e-) is removed and transferred to NAD+ reducing it to NADH + H+.
At one step, a pair of electrons is removed from succinic acid and reduces FAD to FADH2.
The electrons of NADH and FADH2 are transferred to the electron transport chain.
plz check the website for more details :D
