ATP

• What is the definition for ATP?

  The universal energy carrier found in all living cells
• What is ATP short for?

  Adenosine Triphosphate
• can a cell directly get its energy from glucose?

  no
• What happens because a cell cannot directly get its energy from glucose?

  In respiration , the energy released from glucose is used to make ATP
• What is ATP made frOM?

  the nucleotide base adenine, combined with a ribose sugar and three phosphate groups
• ATP is whats known as a......?

  nucleotide derivative
• why is ATP a nucleotide derivative ?

  because it is a modified form of a nucleotide
• what happens once ATP is made?


  It diffuses to the part of the cell that needs energy
• how is the energy in ATP stored?

  Stored in high energy bonds between the phosphate groupd
• how is the energy in ATP released?

  via hydrolysis reactions
• what happens when energy is needed by a cell?


  ATP is broken down into ADP and Pi
• what does ADP stand for?


  adenosine diphosphate
• what does Pi stand for?

  inorganic phosphate
• what type of reaction occurs when ATP ---broken down--> ADP + Pi?

  A hydrolysis reaction

  a phosphate bond is broken and energy is released

  the reaction is catalyzed by the enzyme ATP hydrolase
• How many phosphates does ADP have?
