Reflect and apply What are some of the difficulties in determining the exact number of protons pumped across the inner mitochondrial membrane by the respiratory complexes?
Answer to relevant QuestionsWhy is it difficult to determine an exact number for P/O ratios? Reflect and apply How does mitochondrial structure contribute to aerobic metabolism, particularly to the integration of the citric acid cycle and electron transport? Calculate the net ATP yield from linoleic acid (18:2 D9,12). For this calculation, assume that the loss of an NADPH is the same as the loss of an NADH. (a) Where in an earlier chapter have we encountered something comparable to the action of the acyl carrier protein (ACP) of fatty-acid synthesis? (b) What is a critical feature of the action of the ACP? Would you expect H2O or CO2 to be the source of the oxygen produced in photosynthesis? Give the reason for your answer.
