Metabolic typology of microorganisms

Catabolic (energy-yielding = ATP producing)

• degradation of organic nutrients
• higher molecular weight compunds degraded to lower
• yield CO2 and H2O
• yield precursors for macromolecule synthesis
• yield NADH and NADPH
• yield ATP by:
  • phosphorylation of ADP
  • photophosphorylation (in phototrophs)
  • substrate phosphorylation
  • oxidative phosphorylation (in chemotrophs)

Anabolic (energy-consuming)

• synthesis of monomers and polymers
• degrade organic compounds via specific pathways
• fix CO2
• fix N2
