1) Fill in the blanks: a) This is the site of oxidative phosphorylation in a bacterium b) This electron carrier is found in the membranes c) This complex catalyzes the reduction of O2 2) Five carriers a, b, c, d, e whose reduced and oxidized forms can be distinguished spectrophotometrically, are required for respiration in a bacterial electron-transport system. You know the reduction potential for 4 of the carriers (a = 0.12, c = 0.24, d = -0.02, e = -0.03) In the presence of substrates and oxygen, 2 different inhibitors block respiration, yielding the patterns of oxidation states shown in the Table below: What is the order of the carriers in the chain from substrate to O2? Inhibitor 1 2 Effects of Inhibitors on Carrier Oxidation Levels Carrier a Carrier b Carrier c Carrier d oxidized reduced oxidized oxidized oxidized reduced oxidized reduced Carrier e oxidized reduced
