Gluconeogenesis which of the following reaction is more effective?

For gluconeogenesis which of the following reaction is more effective?

a) Citrate stimulation of Acetyl CoA Carboxylase
b) Acetyl CoA stimulation of Pyruvate Carboxylase
c) Fructose 2,6 Bisphospate stimulates PFK
d) Fructose 1,6 Bisphosphate stimulation of Pyruvate Kinase

Expln

 Citrate stimulation of Acetyl CoA Carboxylase favour Fatty acid synthesis
 Acetyl CoA stimulation of Pyruvate Carboxylase for Gluconeogenesis
 Fructose 2,6 Bisphospate stimulates PFK favour Glycolysis
 Fructose 1,6 Bisphosphate do not favour Pyruvate Kinase
