Consider the following types of cell and their respective conditions: i. a liver cell with non-functional malate-aspartate shuttle* ii. a skeletal muscle cell lacking oxygen iii. a cell with ATP synthase deficiency* iv. a yeast cell undergoing fermentation but with defective alcohol dehydrogenase (hint: In yeast, alcohol dehydrogenase is responsible for shuttling reducing equivalents of cytosolic NADH to the mitochondria.)* V. a brain cell with non-functional Complex II of the electron transport chain* * Assume that the deficiency is isolated and will not influence the function of other respiration components
