    The Citric Acid Cycle Oxidizes Two-Carbon Units .

    Acetyl CoA is the fuel for the citric acid cycle. This important molecule is formed from the breakdown of glycogen (the storage form of glucose), fats, and many amino acids. Indeed, as we will see in Chapter 22, fats contain strings of reduced two-carbon units that are first oxidized to acetyl CoA and then completely oxidized to CO2 by the citric acid cycle.

    15.2: The Citric Acid Cycle - Chemistry LibreTexts

    The Citric Acid Cycle: Capturing Energy from Pyruvate. Aerobic respiration begins with the entry of the product of glycolysis, pyruvate, into the mitochondria. For each initial glucose molecule, two pyruvate molecules will enter the mitochondria. Pyruvate, however, is not the molecule that enters the citric acid cycle.
