ATP

• What is the structure of ATP similar to?

  A nucleotide.
• What are the components of ATP?

  A ribose sugar, an adenine base, and three phosphate groups.
• How many phosphate groups does ATP have?

  Three.
• Where is energy stored in ATP?

  In the bonds between the phosphate groups.
• What enzyme catalyses the synthesis of ATP?

  ATP synthase
• What happens when the bonds between phosphates in ATP are hydrolysed?

  Energy is released.
• What is ATP hydrolysed into?

  Adenosine diphosphate (ADP) and an inorganic phosphate group (Pi).
• What enzyme catalyses the hydrolysis of ATP?

  ATP hydrolase (ATPase)
• What is released during the hydrolysis of ATP?

  Inorganic phosphate (Pi) and energy.
• What can the inorganic phosphate (Pi) released from ATP be used for?

  It can phosphorylate other molecules, making them more reactive.
• What is the role of ATP in cells?

  To provide energy for energy-requiring reactions.
