Step by Step Krebs cycle

Krebs cycle or the citric acid cycle or tricarboxylic acid cycle,occurs in mitochondria, is the common pathway to completely oxidize fuel molecules which mostly is acetyl CoA ,the product from the oxidative decarboxylation of pyruvate.It enters the cycle and passes ten steps of reactions that yield energy and CO2
You can browse the ten steps of reactions through three strands: fact sheet gives the name of enzyme, reaction type,mechanism and prosthetic group; reaction shows the structure of substrate and product(s) and animation presents a short movie clip showing the reaction.
Before going through the TCA cycle, you should know about the oxidative decarboxylation of pyruvate. This reaction links between Glycolysis and TCA cycle.
