Question

The inhibitors of the electron transport chain are substances that bind to some of the components and block the passage of electrons at different points in the chain This inhibition results in the accumulation of reduced forms before the inhibition point whe the inhibitor blocks the flow of electron and oxidized forms of the components of the electron transport chain behind the inhibition point Recall that reduction is gain of electrons whereas oxidation is loss of electrons When a component of the electron transport chain accepts an electron it gets reduced and when it transfers its electrons to an acceptor it gets oxidized and the acceptor becomes reduced For example in the following reaction coenzyme Q is in the oxidized form and accepts an electron to be in the reduced form If we were to add a drug that blocks electron transfer at this step coenzyme Q would remain oxidized and FADH would remai reduced Drag the appropriate labels to their respective targets View Available Hint s Identify the complexes and mobile electron carriers that remain reduced and oxidized due to the following blocker inhibitors You can use the electron transport chain labeled in part A to help answer this question Complex IIl Cytochrome c Complex 1 Coenzyme Q Complex IV Inhibitor Blocker FADH Reduced form Amytal is a painkiller that blocks the flow of electrons to Coenzyme Q Cyanide is a poison that blocks the flow of electrons to oxygen Complex IV Antimycin is an antibiotic that blocks the flow of electrons to Cytochrome c Rotenone is an insecticide that blocks the flow of CoQ FAD CoQH Oxidized form Oxidized form Reduced form Last component that can be Last component that remains reduced due to inhibitor blocker axidized due to inhibitor blocker Reset Help
