he following diagram summarizes the key events in the second stage of aerobic respiration. T arts when two molecules of pyruvate from glycolysis bind with coenzyme A to form acetyl-C OA then enters the citric acid cycle. Examine the diagram closely and then determine the corr iswers. Pyruvate starts with 3 carbon a is converted to acetyl-COA, whic carbon atoms. That missing carl is lost in a molecule of Acetyl-COA brings carbon atoms citric acid cycle. These carbon at passed through many intermedia steps. For example, there are carbon atoms (C) present in oxaloacetate. The citric acid cycle loses itom(s) as carbon dioxide. Which of the following molecules reated during the second stage c erobic respiration and then leave rork elsewhere in the cell? Check hat apply. There is a total of molecules(s) of NADH produced during this entire series of reaction: and 2 ). At the beginning of the second stage of aerobic respiration, pyruvate brings in carbon atoms. By th of the second stage of aerobic respiration, where do those carbon atoms end up? .
