During translation,translocation of the ribosome is driven by which of the following? A)ATP → ADP + P_i B)ATP → AMP + PP_i C)GTP → GDP + P_i D)GTP → GMP + PP_i E)Release of the tRNA in the P site

Question

Quizplus · Accepted Answer

During translation, translocation of the ribosome is driven by GTP hydrolysis, which converts GTP to GDP and phosphate. Therefore, the correct choice is C, where GTP is the energy source for ribosome translocation. The other choices either involve ATP instead of GTP or incorrect products formed from the nucleotide hydrolysis. The release of the tRNA in the P site is a separate step and is not responsible for the energy needed for ribosome movement.
