Question
Please explain... thanks!
After learning about the electron transport chains used in mitochondria and chloroplasts, you decide to try to create your own artificial chain using the molecules F, G, H, J, and K. The redox potentials of these molecules, along with those for NADH and water, are given below. Of the molecules listed above, is there a molecule that is a better electron acceptor compared to oxygen? If so, list those molecule(s). Order the molecules from 1 to 5, in the order they would be used in an electron transport chain, from those that has the lowest affinity for electron to those with the greatest affinity for electrons. F_ G_ H_ J_ K_Explanation / Answer
i)No,there is no molecule found which is a better electron acceptor compared to oxygen as it is extremely electronegative.
ii) The redox potential is a measure of the electron affinity of substance in volts. Thus the order is graded as:
a)F 1 b)G 5 c)H 4 d) J 2 e)K 3
