The human oral microbiota contains over 700 species of bacteria. One species often found in the oral cavity is Streptococcus mutans, an anaerobic bacterium strongly associated with the formation of dental cavities. S. mutans metabolizes glucose and other dietary sugars remaining in the mouth after a meal, producing lactic acid as a byproduct. Over time, high levels of lactic acid can erode tooth enamel, eventually leading to the formation of dental cavities. Which of the following drugs would be most likely to prevent cavities caused by 5. mutans?
A. A drug that inhibits the formation of a proton gradient across the cell membrane
B. A drug that prevents the conversion of glucose into pyruvate
C. A drug that inhibits the production of NADH and FADH2 during the Krebs cycle
D. A drug that prevents the movement of oxygen across the cell membrane
