why the GTP IS used instead of ATP in
Translation elongation and many other cellular processes.?
Is its connected with signalling molecules
ATP is used to carry energy for almost all energy-requiring chemical reactions in almost all cells. GTP can occasionally be used to carry energy, but it is more often used as a signaling molecule. GTP is an energy-rich, activated precursor for RNA synthesis that also plays important roles in several other cellular processes such as protein synthesis, protein localization, signal transduction, visual excitation, and hormone action.
