Answer: Option C.
replenish the citric acid cycle if it becomes depleted of intermediates by biosynthetic demands.
Step-by-step explanation:
Anaplerotic reactions that form intermediates for kreb cycle, citric cycle. They form intermediates for metabolic pathways like citric cycle. The citric cycle is important for energy production and biosynthesis. Anaplerotic reactions help to restore or replenish intermediates in citric cycle if there is depletion of intermediates biosynthetic demands.
