Question

Enzyme enolase catalyses the conversion of 2-PGA to phosphoenol pyruvic acid in the presence of cofactor

• A. $M{n}^{2+}$
• B. $F{e}^{2+}$
• C. $M{g}^{2+}$
• D. $Z{n}^{2+}$

Answer 1

Answer: (C)

$M{g}^{2+}$

Enolase enzyme is also called as phosphopyruvate hydratase. It converts 2 phosphoglyceric acid (PGA) into phosphoenol pyruvic acid (PEP). $M{g}^{2+}$ ion participates in the mechanism or process by stabilizing the negatively charged carboxyl group of Phosphoglycerate (PGA).
So, the correct option is C.
