Concept introduction: The citric acid cycle, also known as Krebs cycle, which consists of series of reactions in the presence of oxygen. WebThe Krebs cycle itself actually begins when acetyl-CoA combines with a four-carbon molecule called OAA (oxaloacetate) (see Figure 4.10.6). This produces citric acid, which has six carbon atoms. This is why the Krebs cycle is also called the citric acid cycle. After citric acid forms, it goes through a series of reactions that release energy.
