The electron transport chain contains four large protein complexes: the NADH-Q reductase complex, succinate dehydrogenase, the cytochrome c reductase complex, and the cytochrome c oxidase complex. What do they have in common?
In electron transfer, only the quinone portion of the ubiquinone undergoes oxidation-reduction; the isoprenoid side chain remains unchanged. What is the function of this chain?
The reaction pictured is an oxidation-reduction reaction in the citric acid cycle in which the energy-carrier molecule NADH is

What effect would this have at the cellular level?arrow_forwardArsenate (AsO³-) closely resembles phosphate in structure and reactivity. However, arsenate esters are unstable and are spontaneously hydrolyzed. If arsenate is added to actively respiring mitochondria, what would be the effect on ATP synthesis? ATP synthesis will decrease because cells require less energy when arsenate is available. ATP synthesis will not be affected because mitochondria are incapable of taking up arsenate. ATP synthesis will stop due to the formation arsenate-ADP anhydrides. ATP synthesis will increase because arsenate anhydride hydrolysis increases ATP turnover. If arsenate is added to actively respiring mitochondria, what would be the most likely effect on the rate of the electron-transport chain? The rate of electron transport will decrease, because arsenate inhibits Complexes I and II. The rate of electron transport will decrease, because arsenate inhibits the citric acid cycle. The rate of electron transport will increase, because arsenate increases the demand…arrow_forward
