Scientists discover more than ten thousand new species of living organisms every year. What is shared between all of these organisms? A. They are made of cells, whose nuclei enclose their DNA. B. They obtain their energy from sunlight. C. They produce and use adenosine triphosphate (ATP). D. Their genome contains at least 1000 genes. E. All of the above.

C. They produce and use adenosine triphosphate (ATP).

Explanation:

ATP is the energy currency for the cells of all living beings. It is produced by aerobic or anaerobic respiration in both prokaryotes and eukaryotes. Complete or incomplete oxidation of nutrients obtains ATP. ATP is used by cells to perform all the vital functions. ATP synthesis occurs when phosphate is added to ADP during substrate-level phosphorylation or oxidative phosphorylation. Hydrolysis of ATP includes the release of terminal phosphate and lots of energy which in turn is used by cells.
