Citric Acid Cycle Summary. The diagram at the left puts the citric acid cycle into perspective as the most important part of metabolism. All of the other types of metabolism feed into it. This is the most important link to the electron transport chain where most of the ATP needed for energy reactions is produced. The initiating step of the citric acid cycle occurs when a four carbon compound (oxaloacetic acid) condenses with acetyl CoA (2 carbons) to form citric acid (6 carbons).
