ATP

• What is adenosine triphosphate (ATP) derived from?

  A nucleotide derivative
• What components make up a single molecule of ATP?

  Ribose, adenine, and three phosphate groups
• What enzyme catalyzes the hydrolysis of ATP?

  ATP hydrolase
• What are the products of ATP hydrolysis?

  Adenosine diphosphate (ADP) and inorganic phosphate (Pi)
• How can the hydrolysis of ATP be utilized in cells?

  It can be coupled to energy-requiring reactions
• What happens to the inorganic phosphate released during ATP hydrolysis?

  It can phosphorylate other compounds
• What effect does phosphorylation have on compounds?

  It often makes them more reactive
• How is ATP resynthesized?

  By the condensation of ADP and Pi
• What enzyme catalyzes the resynthesis of ATP?

  ATP synthase
