Explanation:

In the citric - acid cycle, through a series of enzymatic reactions, citric acid is oxidized and transformed step - by - step back to oxaloacetic acid, which can then combine with another acetyl - CoA to continue the cycle. Citric acid is not changed back to acetyl - CoA directly in the cycle, and it is not used to make glucose in the citric - acid cycle.

Answer:

It is changed back to oxaloacetic acid.
