<prompt> Which coenzyme is responsible for carboxylationreaction?BiotinFADNADHThiamine pyrophosphate  <response>: biotin Biotin is the coenzyme required for enzymes that are involved in carboxylation reactions, e.g. acetyl-CoA carboxylase and pyruvate carboxylase. Most coenzymes are derived from vitamins. Below is given list of vitamins, derived coenzymes and the reactions they are involv ... .
