Now, the second reason why a high ATP concentration basically stimulates this enzyme to carry out its process is because of the following reasoning. So at a high concentration of ATP, when we have many ATP molecules inside our cells, that means we can use the ATP molecules to actually synthesize nucleocide triphosphates or RNA and DNA molecules. But to actually synthesize these nucleic acids, we not only need the ATP, we also need other nucleotide triphosphates, specifically perimedidine nucleocide triphosphates such as CTP. And if we have a high amount of ATP, that usually means we have an unequal distribution of the perimeterine to purine nucleocide triphosphates. And to equalize this distribution of nucleotide triphosphates perimeterine to purine nucleotide triphosphates, we have to carry out this reaction to actually increase the amount of CTP, the perimedidine nucleocide triphosphate that is found inside our cell. So physiologically, a high ATP concentration means that there is an unequal distribution of the nucleocide triphosphates, the purine to perimeidine nucleocide triphosphates, and therefore, the cell tends to equalize this distribution by producing more perimedine nucleotide triphosphates, such as CTT.
