The citric acid cycle is the final common pathway for the aerobic oxidation of fuel molecules. Moreover, as we will see shortly and repeatedly elsewhere in our study of biochemistry, the cycle is an important source of building blocks for a host of important biomolecules. As benefits its role as the metabolic hub of the cell, entry into the cycle and the rate of the cycle itself are controlled at several stages.
