gluconeogenesis
Let an agent explain gluconeogenesis and its regulation, relay the pathway, tissues and physiological roles from biochemistry references, describe its relevance to fasting, exercise and diabetes in general terms, and distinguish gluconeogenesis from glycolysis, glycogenolysis and glycogenesis.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain gluconeogenesis and its regulation, relay the pathway, tissues and physiological roles from biochemistry references, describe its relevance to fasting, exercise and diabetes in general terms, and distinguish gluconeogenesis from glycolysis, glycogenolysis and glycogenesis.
The metabolic pathway that synthesises glucose from non-carbohydrate precursors such as lactate, glycerol and amino acids, occurring mainly in the liver as hepatic gluconeogenesis and to a lesser extent in the kidney and, as recent research describes, the intestine, maintaining blood glucose during fasting and exercise; gluconeogenesis is regulated by hormones such as glucagon and insulin and is a target in diabetes.
What it is for: Not applicable; a metabolic pathway.
It can be explain the pathway; relay regulation and tissues; describe physiological relevance; distinguish related pathways.
Distinguishing features
Glucose synthesis
Liver and kidney
Hormonal control
Fasting role
What it looks like
Not a visible object; a biochemical pathway.
Physical character
main tissue: liver, about 90 percent note
key enzymes: pyruvate carboxylase, PEPCK, fructose-1,6-bisphosphatase, glucose-6-phosphatase list
energy cost: 6 ATP equivalents per glucose note
How it is recognised
Glucose synthesis from non-carbohydrate precursors
Hepatic and intestinal gluconeogenesis
Glycolysis breaks glucose down; glycogenolysis releases glucose from glycogen; glycogenesis stores it
