This diagram shows a step in a reaction where one kind of amino acid is converted into another king of amino acid. Which statement best describes what occurs during this step.
AATP transfers a phosphate group to the original amino acid molecule and becomes ADP.
BAn ATP molecule and an amino acid molecule fit into separate holding spot on the same enzyme.
CThe addition of the new molecule to the original amino acid molecule transforms the original amino acid into a new amino acid
DThe original molecule amino acid, which is now unstable, reacts easily with another molecule and releases the attached phosphate.
This process shown in the diagram is called phosphorylation. Phosphorylation is a significant biochemical process in the body since it is able to activate or deactivate molecules by influencing their chemical properties. An example of a significant phosphorylation process is that of the p53 tumor suppressor protein which is activated by the phosphorylation process.
