Quizplus · Accepted Answer

Large intestine bacteria are responsible for the fermentation of indigestible carbohydrates, such as fiber, which results in the production of short chain fatty acids that serve as an energy source for colon cells and help maintain colon health. These bacteria also play a role in the production of some vitamins, but not vitamins C and D specifically. Gas production is also a byproduct of carbohydrate fermentation, but it is not an essential role played by large intestine bacteria. Bilirubin absorption occurs mainly in the small intestine.
