For ten points, name this gas that is used in photosynthesis and produced by respiration, whose chemical formula is CO2.
In one process, an unstable intermediate formed by adding three molecules of this compound breaks down into 3-phosphoglycerate, and that process is sometimes preceded by one in which this compound is added to form oxaloacetate and malate. An abnormally high amount of this substance in the blood is called hypercapnia and can lead to acidosis, as it forms an acid that is part of the (*) bicarbonate buffering mechanism. Yeast fermentation results in ethanol and this compound, which RuBisCO uses as a source of carbon atoms in the Calvin cycle.
