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

The correct option is C $M{g}^{2+}$

Enolase enzyme is also called as phosphopyruvate hydratase. It converts 2 phosphoglyceric acid (PGA) into phosphoenol pyruvic acid (PEP). This is the eighth step of glycolysis. For the completion of this reaction, the enolase enzyme requires Mg${}^{+2}$ as a cofactor.

Thus, the correct answer is option C.
