Tooth decay is caused by demineralization of the enamel by acids produced by bacteria as they metabolize nutrients ingested by the host. How would these bacteria best be categorized? A. autochemotrophs B. autophototrophs C. heterochemotrophs D. heterophototrophs

Step 1
This rules out options A and B. Second, we know that these bacteria are metabolizing nutrients ingested by the host, which means they are relying on organic substances for their energy and nutrition. This makes them heterotrophs. Show more…

What is the likely cause of tooth decay? A. a lysogenic virus infecting the living cells of the tooth B. bacteria feeding on the sugar in the mouth and producing acid C. an excess of vitamin K production by mouth bacteria D. nitrogen-fixing bacteria releasing ammonia that is eroding the tooth enamel

All of the following attributes of Streptococcus mutans are important in tooth decay except a) it produces endotoxin, which triggers an inflammatory response. b) it can grow at pH below 5 c) it produces lactic acid. d) it synthesizes glucan. e) it stores fermentable polysaccharide.
Streptococcus mutans is a major cause of cavities. It resides in the gum pockets, does not have catalase activity, and can be grown outside of an anaerobic chamber. The bacterium is probably which of the following? a. a facultative anaerobe b. an obligate aerobe c. an obligate anaerobe d. an aerotolerant anaerobe
