Mitochondrial Abnormalities in Tetralogy of Fallot Tetralogy of Fallot (TF) is a genetic disorder in which heart malformations result in abnormal blood circulation, so oxygen does not reach body cells as it should. With insufficient oxygen to accept electrons at the end of miotchondrial electron transfer chains, too many free radicals form. This damages the mitochondriaand the cells. In 2004, Sarah Kuruvilla studied mitochondria in the heart muscle of TF patients. Some of her results are shown in FIGURE 7.13.

As you learned in this chapter, cell membranes arc required for electron transfer phosphorylation. Thylakoid membranes in chloroplasts serve this purpose in photosynthetic eukaryotes. Prokaryotic cells do not have this organelle, but many are photosynthesizers. How do you think they carry out the light-dependent reactions, given that they have no chloroplasts?
How does increasing solute concentration affect water potential? (a) water potential becomes more positive (b) water potential becomes more negative (c) water potential becomes more positive under certain conditions and more negative under other conditions (d) water potential is not affected by solute concentration (e) water potential is always zero when solutes are dissolved in water
In the 1950s, a diet pill that had the effect of poisoning ATP synthase was tried. The person taking it could not use glucose and lost weightand ultimately his or her life. Today, we know that the immediate effect of poisoning ATP synthase is: a. ATP would not be made in the electron transfer system. b. H+ movement across the inner mitochondrial membranewould increase. c. more than 32 ATP could be produced from a molecule ofglucose. d. ADP would be united with phosphate more readily in themitochondria. e. ATP would react with oxygen.
