Match the name of the process with its description Electron transport chain oxidation of pyruvate chemiosmotic phosphorylation citric acid cycle 1. The 2-carbon acetyl group separates from coenzyme A and attaches to a four carbon molecule called oxaloacetate, forming the 6-carbon molecule called citrate. In a series of enzyme-catalyzed steps, the citrate loses 8 high-energy electrons to NAD+ and FAD. In addition, ADP is phosphorylated (changed to ATP) as part of step three. Carbons leave as carbon dioxide in steps 2 and 3. This leaves a 4-carbon molecule, which eventually combines with another Acetyl CoA to form citrate and the cycle begins again. 2. Pyruvate moves into the mitochondrion and two electrons are removed from pyruvate and transferred to NAD+. One of the carbon atoms in pyruvate leaves as a molecule of carbon dioxide. The remaining 2-carbon piece becomes attached to Coenzyme A. 3. Protons concentrated in the inter-membrane space cannot escape, except by traveling through a molecular machine located in the inner membrane of the mitochondrion. This machine or "molecular motor" is called ATP synthase. As the protons move through ATP synthase, they cause a rotor to turn and this movement is used to attach a phosphate group to molecules of ADP, changing them to ATP. 4. Each NADH molecule, coming from step 6 of glycolysis, pyruvate oxidation, and the citric acid cycle delivers two electrons two a carrier molecule located in the inner membrane of the mitochondrion. The electrons then move through a series of carriers, finally arriving at oxygen.
