Study Notes
Microbial Metabolism and Energy Production
- Microbial metabolism plays a crucial role in identifying bacteria by analyzing their metabolic byproducts and energy production pathways.
Energy Production Pathways
- Cellular respiration involves the breakdown of complex organic molecules into simpler compounds, releasing energy in the process.
- Anaerobic respiration uses a final electron acceptor other than oxygen, such as sulfate or nitrate.
- Fermentation is a process that does not require oxygen, generating ATP through substrate-level phosphorylation.
ATP and Energy Production
- ATP (Adenosine Triphosphate) is the primary energy currency of cells, providing energy for various cellular processes.
- Substrate-level phosphorylation is a mechanism used to generate ATP, where ATP is produced directly from the energy released during the breakdown of high-energy molecules.
Enzymes
- Apoenzymes consist of protein alone, acting as a catalyst to facilitate biochemical reactions.
- Enzyme components consist of two parts: apoenzyme (protein part) and cofactor (non-protein part, such as metal ions or coenzymes).
Microbial Energy Sources
- The primary source of energy for microorganisms is the breakdown of organic molecules, such as glucose, through various metabolic pathways.
Glycolysis
- The end product of glycolysis, a key metabolic pathway, is pyruvate.
