F1 isPer ATP synthesised by mitochondrial ATP synthase, the number of H+ that pass through F0 isThe respiratory quotient (RQ) of fat respiration is approximatelyThe maximum natural alcohol concentration in fermentation is limited becauseCytochrome c isIn the TCA cycle, CO2 is released at which step pair?Lactic acid fermentation in muscle differs from alcoholic fermentation in that lactic acid fermentationWhich step of glycolysis is irreversible and a major regulatory point (committed step)?The proton gradient for oxidative phosphorylation is established byIn aerobic respiration of one glucose, the number of CO2 released isAnaplerotic reactions in cellular metabolismEnergy yield per gram of fat vs carbohydrate during respiration isThe end product of glycolysis isNet ATP yield per glucose from glycolysis alone isAlcoholic fermentation produces, besides ethanol,The final electron acceptor in aerobic respiration isThe total ATP yield per glucose by aerobic respiration is approximatelyThe Krebs cycle takes place in thePlants carry out respiration inCompared with anaerobic respiration, aerobic respiration yieldsThe overall reaction of aerobic respiration isGlycolysis takes place inThe net energy yield of glycolysis per glucose isIn plant cells under low-oxygen conditions, pyruvate is typically converted intoThe Krebs cycle takes place inPer turn of the Krebs cycle, acetyl-CoA combines with which molecule first?How many CO₂ molecules are released per glucose by the link reaction plus Krebs cycle?In the electron-transport chain of aerobic respiration, the final electron acceptor isThe textbook total ATP yield per glucose under aerobic conditions is approximatelyThe respiratory quotient (RQ) of a fat-rich seed during germination is closest to
