The diagram shows the structure of adenosine triphosphate (ATP), an essential nucleotide derivative that cells require as an immediate energy source.

Structure of ATP

Which of the following correctly identifies regions X, Y, and Z, and describes the standard reaction catalyzed by ATP hydrolase?

Region X: Adenine; Region Y: Deoxyribose; Region Z: Three phosphate groups; Hydrolysis: ATP+H2O→ADP+Pi\text{ATP} + \text{H}_2\text{O} \rightarrow \text{ADP} + \text{P}_\text{i}ATP+H2​O→ADP+Pi​

Region X: Adenine; Region Y: Ribose; Region Z: Three phosphate groups; Hydrolysis: ATP+H2O→ADP+Pi\text{ATP} + \text{H}_2\text{O} \rightarrow \text{ADP} + \text{P}_\text{i}ATP+H2​O→ADP+Pi​

Region X: Adenosine; Region Y: Ribose; Region Z: Two phosphate groups; Hydrolysis: ATP+H2O→AMP+PPi\text{ATP} + \text{H}_2\text{O} \rightarrow \text{AMP} + \text{PP}_\text{i}ATP+H2​O→AMP+PPi​

Region X: Adenine; Region Y: Ribose; Region Z: Three phosphate groups; Hydrolysis: ATP+Pi→ADP+H2O\text{ATP} + \text{P}_\text{i} \rightarrow \text{ADP} + \text{H}_2\text{O}ATP+Pi​→ADP+H2​O
