which statement is false about complex iii? it holds ubiquinone on the matrix side of the inner mitochondrial membrane throughout the redox process. its functional unit consists of two dimers made up of cytochrome b, cytochrome c1, and the rieske iron-sulfur protein. it couples the oxidation of two molecules of reduced ubiquinone (qh2) with the reduction of two molecules of cytochrome c. it catalyzes the net movement of two protons from the n side to the p side of the inner mitochondrial membrane.

Sagot :

During the redox process, a complex iii does not keep ubiquinone on the matrix side of the inner mitochondrial membrane.

The coenzyme Q: cytochrome c-oxidoreductase, also known as complex III or the cytochrome bc 1 complex, is the third complex in the electron transport chain (EC 1.10.2.2) and is essential for the biochemical synthesis of ATP (oxidative phosphorylation). Complex III shunts electrons to cytochrome c, which then transports them to complex IV. After that, Complex IV reduces oxygen to water using the electrons. Mitochondrial complexes I, II, and III generate superoxide The inhibition of complex III antimycin A prevents the transfer of electrons from either complex I or FADH2-containing flavoproteins to cytochrome.
