In electron transport chain, FADH2 is oxidised to FAD, the electrons are passed to cytochrome proteins whereas hydrogen ions are released into
Options
(a) matrix
(b) outer membrane
(c) cytosol
(d) premitochondrial space
Correct Answer:
cytosol
Explanation:
An electron transport chain or system is a series of coenzymes an cytochromes that take part in the passage of electron from a chemical to its ultimate acceptor. Energy released during passage of electrons from one carrier to the next is made available to specific transmembrane complexex, which pump protons (H⁺) from the matrix side of the inner mitochondrial membrane to the outer chamber or cytosol.Transport of the electrons from NADH over ETC helps in pushing three pairs of protons to the outer cytosol while two pairs of protons are sent outwardly during electron flow from FADH₂ (as the latter donates its electrons further down to the ETC).
