This is the process by which the body obtains its needed glucose supplies by making it from protein rather than taking it directly from the blood sugar which is dumped into the bloodstream by the ingestion of sugars or the breakdown of starches.
Gluconeogenesis
The precursors for gluconeogenesis include lactate, glycerol, and glucogenic amino acids. These substrates can be converted into pyruvate, which then enters the gluconeogenesis pathway to produce glucose.
The starting material for gluconeogenesis is usually pyruvate, which can be converted into glucose through a series of enzymatic reactions. Other precursors such as lactate, amino acids, and glycerol can also be used to generate glucose through gluconeogenesis.
During gluconeogenesis in the postabsorptive state, amino acids and lactate are converted to glucose. Amino acids are primarily derived from muscle protein breakdown and can be used as substrates for gluconeogenesis to maintain blood glucose levels. Lactate is another important precursor for glucose production via gluconeogenesis in the liver.

Cortisol
The anabolic role of gluconeogenesis is to break new glucose molecules from non-carbohydrate precursors.
The fructose-1-phosphate inhibits gluconeogenesis through the enzyme aldolase.
Increased ethanol will give increased NADH. Because NADH levels are higher, the body will produce more pyruvate and less lactate. Since lactate is a precursor for gluconeogenesis, gluconeogenesis will decrease.
Making glucose form an amino acid is a type of a real neat trick. Normally plants make glucose from a reaction involving carbon dioxide and hydrogen with the hydrogen produced from water by photosynthesis. Glucose is a raw material for the production of amino acids. The other way around does not work.

Yes, acetyl-CoA is not glucogenic because it cannot be converted into glucose directly. However, it can indirectly contribute to gluconeogenesis by being converted into oxaloacetate, a key intermediate in the gluconeogenesis pathway.
