Hint: The mitochondria in a double membrane cell organelle, known as the powerhouse of the cell which is present in all eukaryotic cells.
The inner mitochondrial membrane has folds called cristae which help in increasing the surface area.
Complete answer:
> Protein synthesis is carried out by ribosomes. Breakdown of macro moles carried out by various enzymes in the digestive system. Flavoprotein is one of the components of the electron transport chain present in the cristae of mitochondria. Mitochondria are bounded by a double membranous layer. Its inner membrane shows the presence of finger-like projection called cristae. This folded structure increases the surface area for chemical reaction.
> Electron transport system is present in the cristae (inner membrane infoldings of mitochondria).
> It is made up of cytochromes and co-engines which act as carrier molecules and transfer molecules . These molecules accept high energy electrons and pass them to the next molecule in the system. At proton pumping sites, the energy of electrons used to pump protons into the outer component of mitochondria.
These protons are used by synthase to make energy molecules. . This whole reaction is the terminate or ‘Oxidation Reduction’ reaction.
The correct answer is Oxidation Reduction Reaction.
Note: Respiratory chain is located in the inner membrane of mitochondria. It consists of a series of Proteins containing oxidation Reduction groups. Chemical treatment of the mitochondrial membrane results in the isolation of five complexes.
