Microbiology Energy

Stores energy from electron transfer as an ion gradient across the membrane of the cell/organelle

• a metabolic pathway involved in the chemical conversion of carbohydrates, fats and proteins into carbon dioxide and water to generate a form of usable energy.
• glycolysis and pyruvate oxidation before the citric acid cycle, and oxidative phosphorylation after it

Glycolysis - Metabolic pathway that converts glucose into pyruvate

• Strip - oxidoreductase recieves a pair of e^- (usually from NADH which gets them from organic catabolism). each e- travels through FMN + iron sulfer series and are transferred to Quinones (ubiquinone --> ubiquinol)
• energy transfer pumps out 4 H⁺

Pump - A Quinone recieves 2 e^- from oxidoreductase (Ubiquinone is reduced to ubiquinol) and transfers them to terminal oxidase

Energy transfer pumps 2 H's out per quinone

Dump - Terminal oxireductase recieves e- from quinols and transfers them to terminal electron acceptor

2 H's are pumped out

Nitrogenous, sulfer, methanogenesis (uses CO₂ final acceptor), and oxygen
