Question

Quizplus · Accepted Answer

Addition of a phosphate group by a kinase is an example of covalent modification, where the chemical structure of the enzyme is altered by the addition of a chemical group. This changes the catalytic efficiency of the enzyme. The other options do not involve the addition of a chemical group by a kinase.
