Question

Quizplus · Accepted Answer

Phosphatases are enzymes that remove phosphate groups from molecules, essentially reversing the action of kinases. They are not always inhibitory and can alter target activity by removing a phosphate group that was previously added by a kinase. Therefore, option E (all of the above) is incorrect because phosphatases do not always add phosphate groups.
