What is the difference between succinate dehydrogenase and other dehydrogenases?

Succinate dehydrogenase is an enzyme complex which is found in the inner membrane of the mitochondria in case of Eukaryotes.

It is the only enzyme in the body that takes part in electron transport and citric acid cycle.

The pressence of this enzyme shows that there is a pressence of high mitochondrial content in that part of the body

Other dehydrogenases oxidizes a substrate by reducing the electron acceptor which is usually NAD⁺/NADP⁺ or flavin enzyme.
