ATP (Adenosine triphoshate)

• Adenosine triphosphate is a nucleotide derivative and consists of ribose, adenine and

  three phosphate groups.

  
• Energy is released when ATP is hydrolysed to form ADP and a phosphate

  molecule. This process is catalysed by ATP hydrolase.

  
• The inorganic phosphate can be used to phosphorylate other compounds, as a

  result making them more reactive.

  
• Condensation of ADP and inorganic phosphate catalysed by ATP synthase

  produces ATP during photosynthesis and respiration.
