Explanation:
Detailed explanation-1: -Pyruvate decarboxylase (PDC, EC 4.1. 1.1) is the enzyme responsible for the non-oxidative decarboxylation of pyruvate to acetaldehyde and carbon dioxide.
Detailed explanation-2: -Pyruvate is formed as the product of glycolysis. It is converted into acetyl coenzyme A by the process of oxidative decarboxylation, which is catalysed by the pyruvate dehydrogenase enzyme.
Detailed explanation-3: -Hence Pyruvate decarboxylase is a lyase class enzyme.
Detailed explanation-4: -Pyruvate decarboxylation or pyruvate oxidation, also known as the link reaction, Swanson Conversion, or oxidative decarboxylation of pyruvate, is the conversion of pyruvate into acetyl-CoA by the enzyme complex pyruvate dehydrogenase complex.
