The role of GTP in the elongation phase of protein synthesis is to supply energy for
A)peptide bond formation.
B)formation of aminoacyl-tRNA molecules.
C)movement of mRNA along the ribosome.
D)changing the configuration of EF-Tu-GTP.
E)All of the above.

Question

Quizplus · Accepted Answer

GTP provides the energy for changing the configuration of the elongation factor Tu (EF-Tu) when it is bound to GTP, facilitating the correct positioning of aminoacyl-tRNA in the ribosome during protein synthesis.
