atp

• what is atp

  energy transfer within cells - referred as energy currency of the cell
• what does atp contain of

  adenine - nitrogenous base

  ribose - 5-carbon sugar

  phosphates - 3 phosphate groups
• uses of atp in the body

  movement such as muscle contraction

  • active transport of molecules against the concentration gradient
  • synthesis of large molecules such as dna and protein
  • secretion of substances from cells such as releasing hormones from glands
• how is hydrolysis broken down

  addition of water to break a chemical bond between two molecules
• how is condensation broken down

  removal of water to form a chemical bond between two molecules
• Hydrolysis of ATP to release energy

  when water is added to atp it is broken down into ADP and PI.

  the reaction is catalysed by the enzyme ATP hydrolase and releases energy for use in cells
• Condensation reaction to reform ATP

  when a phosphate group and ADP join a water molecule is released. this reaction is catalysed by the enzyme ATP synthase.

  process requires energy and traps chemical energy in the bond
• How the properties of ATP relate to its function

  atp does not work well long term
• How the properties of ATP relate to its function

  hydrolysis of atp release a small amount of energy

  • atp is soluble so it can easily be transported around cells
