Which of the following is most effective for gluconeogenesis in starvation? 
Select and explain. 
A. Acetyl Co-A stimulation of pyruvate carboxylase, B. Fructose-1, 6-biphosphate stimulation of phosphofructokinase-1, C. Citrate stimulation of acetyl carboxylase, D. Fructose-2, 6-biphosphate stimulation of phosphofructokinase-2
A: Acetyl Co-A stimulation of pyruvate carboxylase
Answer: A: Acetyl Co-A stimulation of pyruvate carboxylase 
Explanation: Ans: A(Ref: Harper 30/c 1)1880)Acetyl Co-A stimulation of pyruvate carboxylase is most effective for gluconeogenesis.In Gluconeogenesis, pyruvate carboxylase catalyzes oxaloacetate synthesis from pyruvate.
