During catalysis, succinyl coa synthetase generates (a) an energy rich, unstable phosphoenzyme intermediate(b) an energy deficient, unstable phosphoenzyme intermediate(c) an energy rich, stable phosphoenzyme intermediate(d) all of the above

The correct option is: (C) An energy rich, stable phosphoenzyme intermediate      

Explanation:

Succinyl CoA synthetase is an enzyme, which catalyzes the reaction of succinyl-CoA to succinate. It is a biological reversible reaction. It is a coupling reaction and involves the release of nucleoside triphosphate molecule from a nucleoside diphosphate molecule and a inorganic phosphate molecule.  

During this reaction, formation of an intermediate succinyl phosphate, a  phosphoenzyme takes place. The synthesized phosphoenzyme is an energy rich, stable intermediate.
