Some Bacteria in the Human Gut Microbiota Primarily Feed on Glucose

Some bacteria in the human gut microbiota primarily feed on glucose derivatives from mucus secretions. Which of the following is NOT correct with respect to "mucus farming" by bacteria?

A) Bacteroides thetaiotaomicron and other bacteria induce the colon to produce mucus.
B) Mucus-derived sugar acids are metabolized via the Entner-Doudoroff pathway.
C) Sugar acids must be converted to 6-phosphogluconate in order to enter the Entner-Doudoroff pathway.
D) The glucose derivatives are converted to glucose and degraded via the Embden-Meyerhof-Parnas pathway.
E) This metabolism has been studied via genomics and genetic studies.
