WebAns. a) Nucleic acid EXPLANATION:- ATP or Adenosine triphosphate is a modified nucleotide. An ATP molecule is formed when a nitrogenous base called Adenine is … ATP consists of an adenine attached by the 9-nitrogen atom to the 1′ carbon atom of a sugar (ribose), which in turn is attached at the 5' carbon atom of the sugar to a triphosphate group. In its many reactions related to metabolism, the adenine and sugar groups remain unchanged, but the triphosphate is converted to di- and monophosphate, giving respectively the derivatives ADP and AMP. The three phosphoryl groups are labeled as alpha (α), beta (β), and, for the terminal phos…
