Microbial Metabolism Catabolism provides the building blocks and energy for anabolism. Simple molecules such Heat as glucose,amino acids, released glycerol,and fatty acids Catabolic reactions Anabolic reactions transfer energy from transfer energy from complex molecules ATP to complex to ATP molecules ADP Complex molecules such Heat as starch,proteins,and released lipids Figure 5.1 • Catabolism provides the building blocks and energy for anabolism.
