Release of Succinate from Succinyl-CoA Can Be Coupled to GTP

Multiple Choice

Release of succinate from succinyl-CoA can be coupled to GTP synthesis because:

A) The amide bond between succinate and CoA has a large -DG of hydrolysis.
B) The thioester bond between succinate and CoA has a large -DG of hydrolysis.
C) The link between succinate and CoA involves an acid anhydride to phosphate.
D) Coenzyme A is a "high energy" compound, just like GTP.
E) None of these explains why GTP can be formed during this reaction.
