D)Metabolizing aldosterone and insulin

Question

Quizplus · Accepted Answer

The intestinal bacteria play a role in the metabolism of bile salts, contributing to the intestinal reabsorption of bile and the elimination of toxic bile metabolites. These bacteria also play a role in the metabolism of estrogens, androgens, and lipids, as well as in the conversion of unabsorbed carbohydrates to absorbable organic acids, the synthesis of vitamin K₂, and the metabolism of various nitrogenous substances and drugs. Although they serve many functions, they do not break protein down into amino acids, facilitate colonic motility, or metabolize hormones such as aldosterone and insulin.
