  • What does ATP stand for?
    Adenosine triphosphate
  • Label this ATP molecule
    A) Adenine base
    B) Ribose sugar
    C) Phosphate groups
  • ATP is made by adding a phosphate and energy to ADP (a condensation reaction)
  • ADP is made by adding water to ATP (a hydrolysis reaction)
  • How is ATP formed?
    -in respiration
    -it is a condensation reaction
    -a phosphate and energy is added to ADP
  • How much energy is stored and released in ATP?
    30.6kJ of energy is stored in the high energy bond
    • this is released when ATP is hydrolysed into ADP and a phosphate
  • Why is ATP known as the universal energy currency?
    -it is used to provide energy for all biochemical reactions in all living organisms
  • What are the functions/characteristics of ATP?
    -releases energy in one hydrolysis reaction controlled by one enzyme
    -releases energy in small, usable amounts
    -travels easily to where it may be used
    -used for secretion, muscle contraction, nerve transmission and active transport
