Multiple Choice

Why does the Moeller decarboxylase base medium contain glucose if it is testing the decarboxylation of amino acids?

• A) The decarboxylation of the amino acids takes place during the glucose metabolic pathway. Once glucose is broken down into pyruvic acid, then the amino acid is modified.
• B) To get the energy needed to take the carboxyl group off the amino acid, the bacteria must have glucose.
• C) When glucose is fermented, one of the by-products is acetoin. This acetoin is part of the mechanism that cleaves the carboxyl group from the specific amino acid.
