Electron Transport Chain and Oxidative Phosphorylation (13–24) Select the missing compound, cofactor, name, element, or ion for each of the circles numbered 13–24 on this diagram of the electron transport chain. Some terms may be used more than once, and some terms will not be used at all. Every question has exactly one correct answer. Type in the letter that corresponds with the correct answer from the options below – the options are beneath the image description. Image Description A detailed diagram of oxidative phosphorylation depicting the electron transport chain within the inner mitochondrial membrane. The diagram shows complexes I, II, III, and IV, along with ATP synthase, highlighting the flow of electrons through various carriers like NADH and FADH2. Protons (H+) are pumped into the intermembrane space, creating a gradient. The movement of electrons is coupled with the synthesis of ATP from ADP and inorganic phosphate by ATP synthase, illustrating the overall process of ATP generation. Answer Options A. AMP i. CuA Q.
