WebMar 6, 2024 · Complex II (also called succinate dehydrogenase or succinate-coenzyme Q reductase ) is a membrane bound enzyme of the citric acid cycle that plays a role in the … WebApr 4, 2024 · A bound component of the complex of succinate dehydrogenase (complex II) is FAD. When the substratum succinate binds the complex, it is reduced. - A key concept is the obligatory forcing of protons into the intermembrane space. Without proton translocation, electrons can not pass through Complex I.

WebThe respiratory chain contains 3 multisubunit complexes succinate dehydrogenase (complex II, CII), ubiquinol-cytochrome c oxidoreductase (cytochrome b-c1 complex, complex III, CIII) and cytochrome c oxidase (complex IV, CIV), that cooperate to transfer electrons derived from NADH and succinate to molecular oxygen, creating an … WebComplex II, Succinate-Coenzyme Q Reductase: Components: succinate DH, FAD Inhibitors: none What Happens: 1. Reductase, oxidizes succinate to fumarate (TCA Cycle). 2. electrons are accepted from succinate to produce FADH2. 3. complexes II and III. 4. out protons. Note: Because electrons passing through complex II bypass
WebFeb 2, 2024 · Complex II runs parallel to complex I in the transport chain. However, complex II does not transport protons across the inner mitochondrial membrane, unlike the first complex. Complex II is thus not a part of creating the proton gradient in the ETC.
