Question

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

Answer 1

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

Step-by-step 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.
