The difference between ATP and the nucleoside triphosphates used during DNA synthesis is that:
a. Triphosphate monomers are active in the nucleoside triphosphates, but not in ATP.
b. The nucleoside triphosphates have two phosphate groups; ATP has three phosphate groups.
c. ATP contains three high-energy bonds; the nucleoside triphosphates have two.
d. The nucleoside triphosphates have the sugar deoxyribose; ATP has the sugar ribose.
e. ATP is found only in human cells; the nucleoside triphosphates are found in all animal and plant cells.

The nucleoside triphosphates are components of DNA (deoxyribonucleic acid) so they are composed by a nitrogenous base (adenine, guanine, thymine or cytosine) and a deoxyribose sugar. In contraposition, ATP (adenosine triphosphate) is composed by the nitrogenous base adenine and a ribose sugar along with three phosphates groups. Unlike ribose, deoxyribose is a 5-carbon sugar which lack of an oxygen atom in C2 position.
