<prompt> Carbon mono-oxide CO is released in reaction catalyzed by-DecarboxylasesCarboxylasesHeme oxygenasePyruvate Dehydrogenase  <response>: Heme Oxygenase EC no- 1 catalyzes degradation of Heme by oxygenation and releasing CO in the reaction see fig. With regard to other options which are as follows: DecarboxylasesOption a - produce CO2 Elimination reactions. CarboxylasesOption b - use CO2 as a Substrate. Pyruvate DehydrogenaseOption d - used to conve Pyruvate into Acetyl CoA formed in mitochondria.
