Quizplus · Accepted Answer

The formation of oxaloacetate from phosphoenolpyruvate involves adding a carbon dioxide molecule to the phosphoenolpyruvate in a carboxylation reaction, which is a type of anabolic reaction. This also replenishes the intermediates in the citric acid cycle, making it an anaplerotic reaction as well. Therefore, the best choice is D, all of the above.
