1. 1.

   In an experimental bio-capsule designed for deep-space exploration, synthetic biologists power specialized bioluminescent enzymes exclusively through the hydrolysis of adenosine triphosphate (ATP). As the capsule operates continuously, light emission steadily weakens and eventually halts as ATP is converted into adenosine diphosphate (ADP) and inorganic phosphate. To restore and maintain continuous bioluminescence without adding new chemical supplies, the engineers must supply an external energy source to drive which biochemical process?

   • A) The spontaneous exergonic cleavage of ribose to generate high-energy phosphate bonds
   • B) The hydrolytic condensation of adenine bases from free nitrogenous precursors
   • C) The endergonic phosphorylation of ADP using energy coupling to regenerate ATP
   • D) The irreversible conversion of accumulated inorganic phosphate directly into cyclic AMP
