Here are the essential concepts you must grasp in order to answer the question correctly.
Hydrolysis
Hydrolysis is a chemical reaction involving the breakdown of a compound by water. In biological systems, hydrolysis often refers to the cleavage of bonds in molecules, such as phosphoanhydride bonds in ATP or other phosphorylated compounds, resulting in the release of energy. This process is crucial for metabolic pathways, as it allows for the conversion of high-energy molecules into usable forms.

Curved-Arrow Symbolism
Curved-arrow symbolism is a method used in organic chemistry to depict the movement of electrons during chemical reactions. Arrows indicate the direction of electron flow, with the tail representing the electron source and the head pointing to the electron destination. This notation helps visualize reaction mechanisms, including bond formation and cleavage, which is essential for understanding complex biochemical reactions.

Phosphorylation
Phosphorylation is the addition of a phosphate group to a molecule, often mediated by enzymes known as kinases. This process is vital in cellular signaling and energy transfer, as it can activate or deactivate proteins and other molecules. In the context of ADP phosphorylation, it refers to the conversion of ADP to ATP, a key energy currency in cells, often coupled with exergonic reactions like hydrolysis.
