3 Yeast Metabolism Metabolism refers to the biochemical assimilation (in anabolic pathways) and dissimilation (in catabolic pathways) of nutrients by a cell. Like in other organisms‚ in yeast these processes are mediated by enzymic reactions‚ and regulation of the underlying pathways have been studied in great detail in yeast.
