Rоtenоne is а chemicаl prоduced by some plаnts. For centuries, plants containing this compound have been crushed up and used by indigenous peoples to poison and catch fish. Today, fisheries managers in the U.S. often use rotenone to kill aquatic invasive fish and invertebrate species, such as zebra mussels. Rotenone is toxic to animals because it binds to protein complex I, which is part of the electron transport chain embedded in the inner membrane of the mitochondria. Rotenone inhibits the movement of electrons from complex I. A. Draw this diagram and show the processes that need to occur to produce ATP by oxidative phosphorylation. Be sure to include the function of NADH and FADH2 and O2 in your drawing Electron Transport Chain unlabeled figure.jpgB. Explain how alteration of oxidative phosphorylation processes by rotenone leads to the experimental results shown in figure 1 below. In this diagram CTL is the control treatment where ATP production was measured for cells under normal conditions. ROT is the rotenone treated cells. The affect of rotenone on cells is described in the paragraphs at the beginning of this question. Rotenone ATP decline graph.jpg C. Hypoxia, or lack of oxygen, results in changes in ATP production similar to those seen with the addition of rotenone. Use your knowledge of the cell respiration process to explain why lack of oxygen and exposure to rotenone result in similar changes in cellular ATP production.
