MetaCyc Class: Generation of Precursor Metabolites and Energy

This class contains the pathways of central metabolism (glycolysis, pentose phosphate pathways, and TCA cycle), which collectively produce the 13 starting materials, sometimes termed precursor metabolites, for all cellular biosyntheses. Other degradative pathways, sometimes termed feeder pathways, feed into central metabolism. This class also contains the pathways that generate energy under various conditions of growth.
