Answer:

Requires two Mg²⁺ cofactors and as such demonstrates metal-ion catalysis

Explanation:

Electrostatic catalysis or metal ion catalysis is a catalytic mechanism that makes use of metalloenzymes, such as enolase along with a metal ion which is bound tightly, including, Mo⁶⁺, Ni³⁺, Co³⁺, Mn²⁺, Zn²⁺, Cu²⁺, and Fe²⁺, to undertake a catalysis

For maximal activity, enolase requires the presence of 2 equivalent metal ions in each site which is active

Therefore, the correct option is; requires two Mg²⁺ cofactors and as such demonstrates metal-ion catalysis
