The energy source utilized by the elongation factors EF-G and EF-Tu is:
A) proton motive force
B) ATP hydrolysis
C) GTP hydrolysis
D) phosphoenolpyruvate hydrolysis
E) none is required

Question

Quizplus · Accepted Answer

EF-G and EF-Tu are GTPases, meaning they utilize GTP hydrolysis as an energy source to facilitate protein synthesis. This energy is used to drive conformational changes that allow for movement of the ribosome and tRNA during elongation.
