The enzyme catalysed reaction and the names of the required coenzymes should be determined. Concept introduction: In an enzyme catalysed reaction that requires coenzymes B 12 , a group bonded to one carbon changes places with a hydrogen bonded to an adjacent carbanion. Biotin (vitamin H) is the coenzyme required by enzymes that catalyse the carboxylation of a carbon adjacent to carbonyl group. Coenzymes B 12 : The coenzyme required by enzymes catalyses certain rearrangement reactions.
