Binding of the appropriate aminoacyl-tRNA to the A site requires:
A) no energy input
B) energy supplied by two ATP molecules
C) energy supplied by GTP
D) activation of the A site
E) phosphorylation of the tRNA molecule

Question

Quizplus · Accepted Answer

The binding of the appropriate aminoacyl-tRNA to the A site of the ribosome requires energy supplied by GTP (guanosine triphosphate), not ATP. This process involves the hydrolysis of GTP to GDP and Pi, providing the necessary energy for the accurate positioning and binding of the aminoacyl-tRNA.
