ATP, ADP, NAD+
NADH
CATABOLISM
MODE OF NUTRITIONS FOR MICROORGANISMS
Obtain energy by the
oxidation of electron
donors in their environment.
inorganic
Sulphur, Carbohydrates, Lipid & Proteins
Carbon Dioxide + Sunlight Oxygen + Sugar
Green Plants & Photosynthetic
Bacteria
Use chlorophyll for light-energy capture.
Carbohydrates, fatty acids &
alcohols
STAGES OF CATABOLISM
Glycolysis for glucose, β-oxidation for fatty acids,
Amino acid catabolism
Citric Acid Cycle (Kreb’s cycle)
Electron Transport Chain and ATP synthesis
Carbohydrates
Proteins
Lipids
GLYCOLYSIS
1 glucose 2 pyruvate
2 NADH
2 ATP
KREB’S CYCLEAcetyl CoA + 3 NAD + FAD + ADP + HPO4
-2 --------> 2 CO2 + CoA + 3 NADH+ + FADH+ + ATP
CALVIN CYCLE
1. Make ATP2. Can’t make
NADH3. No oxygen
produced
ANOXYGENIC PURPLE BACTERIA
