Detailed explanation-1: -The structure of Escherichia coli succinate dehydrogenase (SQR), analogous to the mitochondrial respiratory complex II, has been determined, revealing the electron transport pathway from the electron donor, succinate, to the terminal electron acceptor, ubiquinone.
Detailed explanation-2: -NADH and FADH2 are essential to the function of the electron transport chain as electron donors, and are produced during glycolysis and the Krebs cycle to facilitate this process.
Detailed explanation-3: -Succinate dehydrogenase is a TCA cycle enzyme converting succinate to fumarate while reducing FAD to FADH2. SDH is the largest component of the mt-inner membrane Complex II (CII) and thus part of the TCA cycle and electron transfer pathway.
Detailed explanation-4: -Succinate dehydrogenase (SDH), a Krebs cycle enzyme, is an integral component of the mitochondrial respiratory chain complex II, which is composed of four subunits. Three additional proteins, including SDHAF1, are essential for the assembly and activity of SDH.
