Antibiotic Effects on Mitochondria Tetracyclines are antibiotics that inactivate bacterial ribosomes. Knowing that mitochondria evolved from bacteria, researchers suspected tetracyclines might affect mitochondria by harming their ribosomes. FIGURE 19. 11 shows the effects of an experiment in which mice were given either tetracycline or a control antibiotic that affects cell wall production. After 10 days of treatment, the function of mitochondria in the mice was assessed. FIGURE 19.11 Effects of tetracycline on mitochondria. Mice received low-dose tetracycline, high-dose tetracycline, or a control antibiotic that targets bacterial cell walls. Mitochondrial function was assessed by looking at oxygen consumption rate and ATP content in homogenized mouse livers. Bar graphs show means with standard error. An indicates a statistically significant difference between the experimental and the control treatments. How did the two drugs differ in their effect on oxygen consumption by mitochondria?

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. Patient (age) SPO2(%) Mitochondrial Abnormalities in TF Number Shape Size Broken 1(5) 55 + + 2(3) 69 + + 3(22) 72 + + 4(2) 74 + + 5(3) 76 + + + 6(2.5) 78 + + + 7(1) 79 + + 8(12) 80 + + 9(4) 80 + + 10(B) 83 + + 11(20) 85 + + 12(2.5) 89 + + FIGURE 7.13 Mitochondrial changes in tetralogy of Fallot (TF). (A) Normal heart muscle. Many mitochondria between the fibers provide muscle cells with ATP for contraction. (B) Heart muscle from a person with TF has swollen, broken mitochondria. (C) Types of mitochondrial abnormalities in TF patients. SPO2 is oxygen saturation of the blood. A normal value of SPO2 is 96%. Abnormalities are marked +. 3. Can you make any correlations between blood oxygen content and mitochondrial abnormalities in these patients?
