In Mitochondria, Cristae act as sites for

Options

A. Protein synthesis
B. Oxidation-reduction reaction
C. Breakdown of macromolecules
D. Phosphorylation of flavoproteins

Answer

B

Explanation

On the cristae (inner mitochondrial membrane) various proteins are present that helps in the oxidationreduction reaction in electron transport chain.
(1) NADH dehydrogenate complex.
(2) Cytochrome bc, complex.
(3) Cytochrome oxides complex.
Each enzyme contains metal ion either iron or copper in their heme group allows passage of an electron through them. And thus involves in a redox reaction.
