Energy storing compound formed during conversion of succinyl CoA to succinic acid is

Energy storing compound formed during the conversion of succinyl CoA to succinic acid is ATP.
Succinyl-CoA ligase also called succinate synthase, is an enzyme in the Krebs cycle that converts succinyl-CoA to succinate and free coenzyme A, and converts ADP or guanosine diphosphate (GDP) to ATP or guanosine triphosphate (GTP) respectively.
It is converted into succinate through the hydrolytic release of coenzyme A by succinyl-CoA synthetase.
