Correct Answer » C Explanation |

Ans- c- Pyruvate Carboxylase.
When gluconeogenesis is elevated due to low blood glucose levels, the activation by acetyl-CoA of pyruvate carboxylase, which catalyzes the conversion of pyruvate to oxaloacetate, partially alleviates this problem, but in conditions such as starvation and untreated diabetes mellitus, ketone bodies are overproduced and cause ketosis.
