A Correct answer
Explanation

MetaCyc is a curated database of metabolic pathways derived from scientific literature, organized around reference pathway maps that represent consensus metabolic knowledge from diverse organisms. Unlike KEGG's species-specific pathways or EcoCyc's E. coli focus, MetaCyc uses generalized reference pathways as its organizing principle.
