Which of the Following Descriptions Best Matches the Function of a Kinase

Question

Which of the following descriptions best matches the function of a kinase?
A)an enzyme that catalyzes the rearrangement of bonds within a single molecule
B)an enzyme that catalyzes a change in the position of a specific chemical group within a single molecule
C)an enzyme that catalyzes the oxidation of a molecule by removing a hydride ion
D)an enzyme that catalyzes the addition of phosphate groups to other molecules

Accepted Answer

A kinase is an enzyme that catalyzes the addition of phosphate groups to other molecules, typically transferring a phosphate group from ATP to a target molecule. This process is known as phosphorylation and can activate or deactivate a molecule, altering its function in the cell.
