Detailed explanation-1: -One reason for this is that all of the other kinases require two substrates: a phosphate donor and ADP. Obtaining a high degree of purity in the reagents is consequently made more difficult. Adenylate kinase uses two ADP molecules with one as the phosphate acceptor and the other as the phosphate donor.
Detailed explanation-2: -Adenylate kinase (AK) is a ubiquitous and abundant enzyme catalyzing the phosphoryl transfer between two adenosine diphosphate (ADP) molecules to yield adenosine triphosphate (ATP) and adenosine monophosphate (AMP).
Detailed explanation-3: -Because the substrate for pyruvate kinase is a simple phospho-sugar, and the product is an ATP, pyruvate kinase is a possible foundation enzyme for the evolution of the glycolysis cycle, and may be one of the most ancient enzymes in all earth-based life.
Detailed explanation-4: -When ADP is broken down into ATP, energy is released. 3. ATP is synthesized by the cell through cell respiration.
