Why does the reversal of pyruvate kinase's action in glycolysis require two steps in gluconeogenesis?

How does oxaloacetate function in both gluconeogenesis and the citric acid cycle?

Evaluate the mechanism by which fructose 1,6-bisphosphatase reverses the action of phosphofructokinase in gluconeogenesis.

Analyze the differences between the enzymes that reverse reactions 10, 3, and 1 of glycolysis during gluconeogenesis.

How does PEP carboxykinase utilize GTP in the conversion of oxaloacetate to PEP?

Propose a scenario where gluconeogenesis is impaired. How would this affect blood sugar levels and liver function?

How do phosphatases function in gluconeogenesis to reverse kinase actions from glycolysis?
