1 molecule of glucose can generate 38 molecules of ATP via aerobic respiration in prokaryotes. And why is it never the case in reality? - CORRECT ANSWERS--Glucose never generates 38 ATP in reality • The PMF generated from ETC is never used only to generate ATP • Bacteria spend some of their PMF energy to maintain stable ion gradients during extreme changes in external pH and oxygen levels • Bacterial also have other cell processes that use PMF directly. E.g. flagellar rotaAon, nutrient uptakes via H+ symport/anAport, efflux pump (pump toxic drugs out of the cell) 27. Nutritional adaptation of fungi (acidophil, tolerate higher osmotic pressure and lower moisture level) - CORRECT ANSWERS--• Fungi are chemoheterotrophs • Compete with bacteria for food
