Which is correct regarding electron transport chain complex III?Group of answer choicesContains Heme B which is capable of donating a pair of electrons.The overall stoichiometry of its reaction requires 2 cytochrome c for every ubiquinol.The oxidation of cytochrome C is coupled to the pumping of four protons into the mitochondrial intermembrane space.The lipid soluble cytochrome c transports electrons to complex IV.

The electron transport chain: A. involves four protein complexes (I, II, III and IV) all of which are proton pumps. B. Uses ubiquinol as a mobile electron transporter to deliver electrons to complex III. C. intersects with the Krebs cycle, because isocitrate dehydrogenase is the same as complex III. D. increases in the concentration of hydrogen ions in the mitochondrial matrix.

The final electron acceptor in the electron transport chain is: A. H2O B. NAD C. Sitochroom c / Cytochrome c D. Molekulêre suurstof / molecular oxygen

Complex I of the electron transport chain accepts electrons from _____ A. Cyt c B. NADH C. CoQ D. ATP E. FADH2

Complex IV receives electrons from _____ and tranfers the electrons to ______? A. FADH2 - suurstofFADH2 - oxygen B. Kompleks III - Kompleks VComplex III - Complex V C. KoQ - sitochroom cCoQ - cytochrome c D. Sitochroom c - suurstofCytochrome c - oxygen

Which of the following statements about Complex II of the respiratory chain is accurate?Group of answer choicesComplex II pumps 4 H+ into the intermembrane space for every 4 e- that pass throughComplex II passes electrons to Complex IIIComplex II receives electrons from NADHComplex II is an enzyme that catalyzes a reaction in the citric acid cycle.Two or more of the above are true
