Most of the co2 from the catabolism of glucose is released during

The correct answer is "the citric acid cycle".

Explanation:

Because of its role in energy production and biosynthesis, the citric acid cycle is one of the most important pathways in cellular metabolism. Much of the CO2 generated by catabolism is released via the citric acid cycle. This is accomplished by releasing two molecules of CO2 per cycle switch, using the two carbon atoms from acetyl CoA.
