You Are Trying to Figure Out an Electron Transport Pathway

question 20

Multiple Choice

You are trying to figure out an electron transport pathway including the following electron transport molecules: B, K, T, Q and X. You do so by employing inhibitors for various steps in the process. When you do, you get the following results: Inhibitor Electron Transport Molecules Trapped in Reduced Form
Ticin Q & K
Digitin K
Estin T, K, Q & B
Lucin Q, K & T
What is the order of the molecules (the pathway) in the electron-transport chain suggested by the above data from the most reduced to the least reduced molecule?

• A)K -> T -> B -> Q -> X
• B)K -> X -> B -> Q -> T
• C)K -> Q -> T -> B -> X
• D)X -> B -> T -> Q -> K
• E)T -> B -> K -> Q -> X
