The third phosphodiester bond of ATP is broken mostly. The rest of the molecule is called Adenosine Diphosphate or ADP.
<h3><u>Explanation:</u></h3>
For knowing the answer, we need to know the structure of ATP first. ATP or the Adenosine Triphosphate is also called the energy currency of living cell. It has two components -
A. Adenosine which is actually an Adenine nitrogen base attached with a ribose sugar molecule.
B. Phosphate molecules.
The structure of Adenosine Triphosphate is a ribose sugar which is attached with one adenine molecule with which one phosphate ion is attached and the rest of the phosphate ions are attached with the phosphate one after the other.
Ribose - Adenine - Phosphate - Phosphate ~ Phosphate.
The last phosphodiester bond between the two phosphates is the most energetic bond containing maximum of the energy. This bond is broken during the metabolic processes to supply energy to the processes.
The site in a polynucleotide chain as to where the restriction enzyme cleaves nucleotides by hydrolyzing the phosphodiester bond between them.
