This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: None, Subject name: Biochemistry
Insulin increases the following pathways in liver EXCEPT: 
Select and explain. 
A. Fatty acid synthesis, B. Glycogen synthesis, C. Protein synthesis, D. Glucose synthesis
D: Glucose synthesis
Answer: D: Glucose synthesis 
Explanation: Hormonal regulation

Insulin generally favours all pathways which decrease blood glucose level by dephosphorylating the regulatory enzymes of these pathways
In other words enzymes active under the influence of insulin is active in the dephosphorylated state.
Glucagon generally favor all pathways which increase blood glucose level by phosphorylating the regulatory enzymes of these pathways
In other words enzymes active under the influence of glucagon is active in the phosphorylated state.
