21. This process consumes large amounts of adenosine triphosphate ( ATP ), the energy source of the cell. 22. The species is of some interest to researchers, who make use of its acetylcholinesterase and adenosine triphosphate . 23. Adenosine is an ingredient in adenosine triphosphate ( ATP ) and also a product of ATP metabolism. 24. It prevents amino acid incorporation into proteins and interferes with cellular use of adenosine triphosphate ( ATP ). 25. Mineral nutrients are absorbed actively by the root cells due to utilisation of adenosine triphosphate ( ATP ). 26. It forms adenosine triphosphate ( ATP ), a nucleoside triphosphate, when three phosphate groups are added to adenosine. 27. Gefitinib inhibits EGFR tyrosine kinase by binding to the adenosine triphosphate ( ATP )-binding site of the enzyme. 28. Creatine is stored in muscles and allows muscles to regenerate adenosine triphosphate , the major fuel used in explosive movements. 29. Leaves also ATP ( adenosine triphosphate ), which acts as an energy currency for metabolism in all living things. 30. GTP is used instead of adenosine triphosphate ( ATP ), so the reaction is not dependent on its products.
