Does the energy required to add the amino acid the the tRNA molecule come from GTP hydrolysis or ATP hydrolysis? I know the reaction is catalyzed by the enzyme aminoacyl tRNA synthetase, I am just confused if on whether the energy is in the form of ATP or GTP.

Aminoacyl tRNA synthetases use ATP as their energy source to charge a tRNA with the appropriate amino acid.
