Question

Enzyme encolase catalyses the conversion of $2$PGA to phosphoenol pyruvic acid in presence of ____________, which is the cofactor.

• A. $M{n}^{++}$
• B. $F{e}^{++}$
• C. $M{g}^{++}$
• D. $Z{n}^{++}$

Answer 1

The correct option is C $M{g}^{++}$

Enolase is a metalloenzyme responsible for the catalysis of the conversion of 2-phosphoglycerate (2-PG) to phosphoenolpyruvate (PEP), the ninth and penultimate step of glycolysis. In this reaction magnesium ion acts as a cofactor.
