What is the function of GTP in translation?
A) GTP energizes the formation of the initiation complex, using initiation factors.
B) GTP hydrolyzes to provide phosphate groups for tRNA binding.
C) GTP hydrolyzes to provide energy for making peptide bonds.
D) GTP supplies phosphates and energy to make ATP from ADP.
E) GTP separates the small and large subunits of the ribosome at the stop codon.

Question

Quizplus · Accepted Answer

GTP plays a key role in translation by energizing the formation of the translation initiation complex, which is composed of the small ribosomal subunit, initiator tRNA, and initiation factors. GTP is hydrolyzed to GDP after initiation complex is formed, allowing the large ribosomal subunit to join and the elongation phase of translation to begin.
