Bacterial Metabolism

1
Bacterial Metabolism

• Oxidative Phosphorylation

2
Bacterial Catabolism

• Oxidative phosphorylation - Includes
• uses oxygen as final electron acceptor
• oxidizes NADH and FADH
• ATP Synthesis
• Uses membrane potential

3
Bacterial Catabolism

• Oxidation of NADH FADH
• regenerates NAD FAD for Krebs cyccle
• 3 ATPs produced for each NADH
• 2 ATPs produced for each FADH

Bacterial Catabolism
5
Bacterial Catabolism

• 10 NADH (2 from glycolysis and 8 from Krebs
  cycle) yield 30 ATP per glucose
• 2 FADH (from Krebs cycle) yields 4 ATP
• 2 ATP from Krebs cycle
• 2 ATP from Glycolysis
• 38 ATP produced per molecule of glucose oxidized
