ATP

• What is the structure of ATP?

  ATP (adenosine triphosphate) consists of an adenine base, a ribose sugar, and three phosphate groups.
• How is ATP formed?

  During respiration and photosynthesis.

  Condensation reaction and ATP synthase catalyses it.

  ADP + Pi = ATP + H2O
• How is ATP formed?

  During respiration and photosynthesis.

  Condensation reaction and ATP synthase catalyses it.

  ADP + Pi = ATP + H2O
• What is the importance of the hydrolysis of ATP?

  Releases energy, produces an inorganic phosphate ion which can phosphorylate other molecules.
• ATP hydrolase does what?

  Catalyses ATP hydrolysis
• What are the roles of ATP?

  Movement (muscle contraction).

  Metabolic Processes (building macromolecules).

  Transport across membranes (Active transport).
• Why is ATP better than glucose as an energy source?

  Releases energy after a single reaction rather than a long series of reactions.

  Releases a more manageable quantity of energy each time.
