metabolic pathway
Let an agent explain metabolic pathways and their regulation, support learning and research with pathway databases, and relate pathway defects to health at a general level.
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 metabolic pathways and their regulation, support learning and research with pathway databases, and relate pathway defects to health at a general level.
A linked series of chemical reactions in a cell, catalysed by enzymes, that converts substrates into products, such as glycolysis, the citric acid cycle, fatty acid synthesis and photosynthetic pathways, organised into catabolic and anabolic routes and interconnected into metabolic networks; pathways are regulated and their defects cause metabolic diseases.
What it is for: Cellular energy, biosynthesis and biochemistry.
It can be explain a pathway and its steps; describe regulation and integration; find pathway databases; relate pathway defects to diseases in general terms.
