Q. Identify the biocatalyst that helps in obtaining the connecting link between glycolysis and Kreb's cycle.

NTA AbhyasNTA Abhyas 2022

Solution:

2 molecules of Pyruvate are formed by the glycolytic reaction occurring in the cytosol of the cell. The pyruvate molecule then enters the mitochondrial matrix where it is converted to Acetyl-CoA by a reaction known as oxidative decarboxylation in presence of oxidizing agent NAD+. The enzyme responsible for this reaction is pyruvate dehydrogenase and the cofactor is $M g^{+ +}.$
