WebOct 26, 2024 · Brief Answer. GTP, rather than ATP, is used for nuclear–cytoplasmic transport via importins and exportins, because this process involves one of a large family of ‘G proteins’ that — as their name implies — operate through the use of GTP. Whereas ATP is generally used to drive endergonic molecular reactions, the hydrolysis of GTP in G ... WebSubstrate-level phosphorylation is a metabolism reaction that results in the production of ATP or GTP supported by the energy released from another high-energy bond that leads to phosphorylation of ADP or GDP to ATP or GTP (note that the reaction catalyzed by creatine kinase is not considered as "substrate-level phosphorylation"). This process uses …
