Re: Why is ATP rather than GTP, CTP or TTP the energy currency?

... 3 dimensional structure of the final product (protein) is useless and it means all the energy used for the synthesis is wasted ... ! So when the “accuracy and order” is primarily important – GTP is preferred for the ` selective evolutionary force` for error free protein synthesis ( almost all ...
