Which of the following statements concerning ATP synthesis in mitochondria is FALSE? a. interruption of the flow of electrons from NADH to oxygen would decrease ATP synthesis b. making the inner mitochondrial membrane permeable to H+ would decrease ATP synthesis c. the energy liberated by the electron-transport chain is used to pump H+ ions into the IM-space d. the movement of H+ through a special channel enzyme (synthase) results in ATP synthesis e. when protons move from the matrix to the IM-space, ATP is made from ADP + Pi
Cyanide is a poisonous substance. Cyanide is a cytochrome c oxidase inhibitor that is competitive. The last enzyme of the electron transport chain in mitochondria is cytochrome c oxidase. One of the most common substrates for cytochrome c oxidase is oxygen.Would an increase in the concentration of oxygen affect the inhibitioncaused by cyanide?How would conditions in the mitochondrial intermembrane spacechange if cytochrome c oxidase and the electron transport chain are notfunctioning properly.. Explain why this change in conditions will be harmful to a cell.
