What are the differences between nucleoside triphosphate and nucleotide triphosphate, and how do these molecules function in cellular processes?

Nucleoside triphosphate is a molecule consisting of a nucleoside (sugar and nitrogenous base) and three phosphate groups, while nucleotide triphosphate includes a nucleoside, phosphate groups, and additional functional groups. Both molecules serve as energy carriers in cellular processes, providing the energy needed for various biochemical reactions. Nucleoside triphosphates are involved in DNA and RNA synthesis, while nucleotide triphosphates are essential for protein synthesis and cell signaling.
