ATP is the main energy currency in cells, and it can especially be used to drive condensation reactions that produce macromolecular polymers. How does ATP normally catalyze the condensation reaction, which by itself is energetically unfavorable?

A) It transfers its terminal phosphate to an enzyme and is released as ADP.
B) It transfers its two terminal phosphates to an enzyme, and is released as AMP.
C) It covalently attaches to both of the substrates.
D) It transfers either one or two terminal phosphate(s) to one of the substrates and is released as either ADP or AMP.
E) It covalently attaches to the enzyme, forming an enzyme-AMP adduct.
