Bacterial metabolism3

  1. 1. BACTERIAL METABOLISM  All chemical processes present in bacterial cell  Divided into: Anabolism processes: synthesis of cell components Catabolism processes: breakdown cell components for energy generation  Vary, depend on nutrition  Pathogen bacteria : heterotrophic  Enzymes play role in metabolism
  2. 2. METABOLISM ENERGY USAGE:  Grow  Replication & multiplication  Replace a new components cell  Heat  Luminesention  Fermentation process  Respiration process  Photosynthesis process
  3. 3. ENZYMES in metabolism:  Dehydrogenises reduction & oxidation  Flavoprotein electron transfer  Iron Porphyrin Protein Enzyme respiration Example : - catalase - peroxidase - cytochrom oxidase
  4. 4. CARBOHYDRATE METABOLISM  Prominent source of carbon for both aerobe & anaerobe bacterial  Source of energies  For amino acid, lipid, carbohydrate, purine etc  Cleavage of glycoside binding by hydrolysis, phosphorilation, transglycosidation
  5. 5.  Carbohydrate --------Thriose (Phosphate & Pyruvate)  Enzymes:  glycosidase  phosphorilase  Example: Glucose pyruvic acid (Embden-Meyerhoff Cycle)
  6. 6. EMBDEN MEYERHOFF CYCLE:  Glucose  Glucose 6 phosphate  Phosphooglyseraldehide  Phosphooenol pyruvate  Pyruvate PENTOSA PHOSPHATE CYCLE  Glucose  Glucose 6 phosphate  Pentose phosphate
  7. 7. ENTNER DOUDOROFF CYCLE  Glucose  Glucose 6 phosphate ketodeoxy gluconate  piruvate +  gliseraldehide PIRUVAT FERMENTATION PRODUCES:  Alcohol  lactate acid  butyric acid  propionic acid  acetic acid
  8. 8. LIPID METABOLISM  Similar to carbohydrate metabolism  Starting with lipid acid activation by CoA glyserol+acetylCoA  Acetyl-coA Krebs's Cycle
  9. 9. AMINO ACIDS METABOLISM Amino acid was metabolized through:  deamination: R--C--C--C = O R--C--COOH + NH2 NH2 OH  transamination  decarboxilation: R--CH----COOH R----CH2NH2 + CO2 NH2 decarboxilase
