Unformatted text preview: Cellular Metabolism • Requires chemical energy which is provided by the oxidation of glucose • Glucose is oxidized through a series of enzymatic reactions that produce Carbon dioxide Water ATP • C 6 H 12 O 6 6 H 2 O + ATP • Oxidation of Glucose Glycosis Krebs Cycle (aka Citric Acid Cycle) • Glycosis Anaerobic--occurs in absence of oxygen Takes place in cytoplasm Produces pyruvate o Can be further metabolized by another series of anaerobic reactions called fermentation o Results in alcohol and carbon dioxide • Cellular respiration Aerobic--dependent on oxygen Krebs Cycle and electron transport chain Takes place in mitochondria Produces more ATP • Redox reactions Chemical oxidation--molecules lose electrons (LEO--lose electrons oxidation) Chemical reduction--molecules gain electrons (GER--gain electrons reduction) • Anaerobic respiration Fermentation--cells break down glucose to form ethanol, CO 2 , and 2 ATP C 6 H 12 O 6 2C 2 H 5 OH + 2CO 2 + 2ATP (glucose ethanol + carbon dioxide + energy) Bromothymol blue o Forms carbolic acid in the presence of CO...
