ATP

• WHAT IS ATP MADE UP OF?

  adenosine (adenine + ribose sugar) and 3 phosphate groups
• WHAT DOES ATP STAND FOR?

  adenosine triphosphate
• PRODUCTION OF ATP?

  during respiration using ATP synthase (catalyses ADP + Pi)
• HYDROLYSIS OF ATP?

  into ADP + Pi, using ATP hydrolase which releases a small amount of energy
• WHAT IS ATP?

  a nucleotide derivative (immediate source of energy for biological processes)
• WHY IS ATP NEEDED?

  metabolic reactions in cells require constant, steady ATP supply
• WHAT IS ANOTHER USE OF ATP?

  can transfer energy to other compounds (Pi released in hydrolysis of ATP bonded to different compounds to make them more reactive)

  -> PHOSPHORYLATION
