The three major components of ATP i.e Adenosine triphosphate include
a) A nucleotide base – adenine which is in ring form
b) A ribose
c) Three phosphate group
While ADP i.e Adenosine di phosphate has all its constituents similar to ATP except the “three phosphate group”. ADP has two phosphate groups. Similarly RNA and DNA also have structure similar to ATP but the number of phosphate group is not specifically three in number. Thus Option is the most prominent choice among all the given options.
Adenosine triphosphate (ATP) is known to be a complex organic compound that functions by providing energy to drive many biological processes in living cells. The building blocks of ATP is made up of Adenine, ribose sugar and three molecules of phosphate group. Furthermore, ATP is a molecular unit currency of intracellular energy transfer and large amount of energy is released during its hydrolysis.
Having a repetitive enzyme system would allow more than one enzyme to catalyze a particular reaction. If one of the types of enzyme is not able to perform its function due to temperature or any other factor, then another kind of enzyme would be able to catalyze the reaction. Hence, having repetitive enzyme systems is very effective in carrying out the metabolic functions of the body even when conditions are not favourable.
