Question
The synthesis of purines from its constituents is very expensive. Which of the following describes the energetic costs of synthesizing purines?
It costs 8 ATP equivalents to synthesize one AMP and 9 ATP equivalents to synthesize one GMP from ribose.
The use of ATP to synthesize GMP and the use of GTP to synthesize AMP helps to balance the synthesis of these purines.
Once AMP and GMP are synthesized more energy is needed to convert them into triphosphates in the nucleoside kinase reactions.
