11. She initially worked with Francis Crick on transcoding protein chains and aromatic adenosine triphosphate . 12. One central coenzyme is adenosine triphosphate ( ATP ), the universal energy currency of cells. 13. These reactions require energy, known also as an hydrolysis of adenosine triphosphate ( ATP ). 14. The DNA is " labeled " by the addition of radioactive Phosphate derived from Adenosine Triphosphate . 15. Adenosine triphosphate , or ATP, acts as a free energy " currency " in all living organisms.16. Bacteria normally break down glucose to generate adenosine triphosphate _ the main energy source for cells. 17. Photosynthesis converts light energy into chemical energy in the form of adenosine triphosphate ( ATP ). 18. DNA ligase from eukaryotes and some microbes uses adenosine triphosphate ( ATP ) rather than NAD. 19. Another key component of life, the energy-transporting molecule adenosine triphosphate , was synthesized in Ponnamperuma's laboratory at Ames. 20. Furthermore, SGCs also possess mechanisms to release cytokines, adenosine triphosphate ( ATP ), and other chemical messengers.
