Kinases are enzymes that
A)add phosphate groups.
B)do not alter target activity.
C)are always inhibitory.
D)remove phosphate groups.
E)all of the above

Question

Quizplus · Accepted Answer

Kinases are enzymes responsible for adding phosphate groups to other molecules, typically proteins. This process, known as phosphorylation, can alter the activity of the target molecule. Therefore, option A is the correct answer. Option D is incorrect because removing phosphate groups is carried out by phosphatases, not kinases. Option B is incorrect because the addition of phosphate groups by kinases does alter the activity of the target molecule. Option C is incorrect because the activity of kinases can be both inhibitory and stimulatory depending on the context.
