An enzyme active site contains a lysine that acts as through electrostatic catalysis (proximity and orientation). It has a pka = 10. Fill in the blanks in the following paragraph. In order for the lysine residue to work in this manner, it must be in a [Select] form. The efficiency of the enzyme will be (Select] when pH is greater than

An enzyme active site contains a lysine that acts as through electrostatic catalysis (proximity and orientation). It has a pka = 10. Fill in the blanks in the following paragraph. In order for the lysine residue to work in this manner, it must be in a [ Select] form. The efficiency of the enzyme will be [Select] when pH is greater than the pKa (compared to when the pH is less than the pKa). At pH = 11, for example, the enzyme will %3! achieve approximately [Select] * % of the electrostatic catalysis associated with this amino acid. One would also expect to see a greater degree of electrostatic catalysis if water [Select] * the active site upon substrate binding. was
