Plants have the type that produces ATP (ADP - forming succinyl - CoA synthetase). Several of the enzymes in the cycle may be loosely associated in a multienzyme protein complex within the mitochondrial matrix . </P> <P> The GTP that is formed by GDP - forming succinyl - CoA synthetase may be utilized by nucleoside - diphosphate kinase to form ATP (the catalyzed reaction is GTP + ADP → GDP + ATP). </P>
