The enzyme enolase has a permanently bound Mg2+ ion in its active site. To the below is a schematic of the enzyme active site bound to an intermediate of the reaction. Which of the following are true? (Pick two.) PO32- Н Mg2 C C H HO Favorable electrostatic interactions (dashed blue lines) between Mg2+ and the intermediate increase (make it more positive) the AG of the reaction. Favorable electrostatic interactions (dashed blue lines) between Mg2+ and the intermediate decrease (make it more negative) the AG of the reaction. Favorable electrostatic interactions between Mg2+ and the intermediate decrease the rate constant, k, of the reaction, decreasing the rate of the reaction. Favorable electrostatic interactions between Mg2+ and the intermediate increase the rate constant, k, of the reaction, increasing the rate of the reaction.
