Which is NOT true about protein kinases?
A)They add phosphate groups to proteins.
B)They produce effects similar to allosteric modulation.
C)They perform the opposite function as phosphatases.
D)They use ATP to carry out their reactions.
E)They remove phosphate groups from proteins.

Question

Quizplus · Accepted Answer

Protein kinases add phosphate groups to proteins, often resulting in the activation of the protein. They use ATP to carry out their reactions and produce effects similar to allosteric modulation. Phosphatases, on the other hand, remove phosphate groups from proteins, which can result in the inactivation of the protein. Therefore, choice C is false, but choice E is true for phosphatases.
