The phosphorylation of ADP to produce ATP is endergonic because
A) a negatively charged ion is bonded to a molecule that already carries a negative charge
B) ATP is more stable than ADP
C) the entropy of the products is less than that of the reactants
D) polyphosphate chains are the storage form of phosphorus in living organisms

Question

Quizplus · Accepted Answer

The phosphorylation of ADP to ATP is endergonic because it involves the addition of a negatively charged phosphate group to ADP, which already carries negative charges, making the process energetically unfavorable and requiring energy input.
