Anaerobic respiration ORGANIC ACID IS PRODUCE (ALDEHYDE OR ALCOHOL), PRODUCT IS NOT INORGANIC (EX IS MANNITOL-ORGANIC) Fermentation Glycolysis only Substrate level phosphorylation only NO ELEC PULLED OFF No net oxidation of substrate Terminal electron acceptor is an organic molecule HOMOFERMENTER: PATHWAY LEADS TO ONE PRODUCT HETEROFERMENTER: PATHWAY LEADS TO MORE THAN ONE PRODUCT Fermentation ORGANISM THAT FERMENT GROW SLOWLY BECAUSE THERES LESS NRG DUE TO SUBSTRATE LEVEL PHOSPHORYLATION ONLY. NO NET OXIDATION OF SUBSTRATE TERMINAL ELEC ACCEPT IS ORGANIC MOLEC (PYRUVATE/ ETHANOL/LACTIC ACID, ECT) Terms: TYING IN CONCEPTS: HETEROFERMENTER; SACCHAROMYCES CEREVISIAE: PASTEUR INVESTIGATED WINE SPOILAGE; Respiration PRESENCE OF AIR JUICE SUGAR BECOMES ETHANOL THEN ACETIC Aerobic respiration ACID; ROUND ORGANISM PRODUCED DURING FERMENTATION (YEAST CELLS) ABSENCE OF AIR Anaerobic respiration ---> LEADS TO CARBON DIOXIDE+ETHANOL CLOSTRIDIUM: FERMENTATION YIELDS BUTARATE AND Fermentation ACETONE; PASTUER+AEROBIASIS; ANAEROBIC ORG.
