Chapter 12, Problem 12.15EP

Interpretation Introduction

Interpretation: To specify the structural unit present in ATP in terms of name and the number.

Concept introduction: Nucleotide is the basic unit required for the formation of nucleic acid which is required for completion of various metabolic reactions. The basic structure of nucleotide consists of three units: nitrogen-containing base, a pentose sugar, and a phosphate group. The nitrogen-containing base and pentose sugar are collectively known as a nucleoside. A nucleoside unit attached to a phosphate group together forms a nucleotide unit.

ATP is also a nucleotide which provides energy for the various metabolic reaction. The reaction is:

${\text{ATP + H}}_2\text{O}\to {\text{AMP + 2P}}_{\text{i}}+2{\text{H}}^{+}\text{+energy}$
