Which function performs complex I of electron transport chain system: Transport of protons into the innermembrane space
Oxidation of NADH2 by coenzyme Q
Oxidation of cytochrome b by cytochrome c1
Oxidation of FADH2 by coenzyme Q
transports electrons from Cyt c to O2.

Oxidation of NADH2 by coenzyme Q

Explanation:

Complex I (NADH-ubiquinone oxidoreductase) is the first enzyme of the electron transport chain, which is located in the inner mitochondrial membrane of eukaryotic cells. The main role of this complex is to oxidize nicotinamide adenine dinucleotide H (NADH) which is donated from glycolysis and the citric acid cycle and transfer 2 electrons from NADH to flavin mononucleotide (FMN). Subsequently, these two electrons are used to reduce Coenzyme Q (i.e. ubiquinone) to ubiquinol. Ubiquinone is a fully oxidized coenzyme Q10, whereas ubiquinol is a fully reduced form of this enzyme.
