Using the data of Figure 3.10, predict the sequence of electron carriers in the membrane of an organism growing aerobically that has the following electron carriers: ubiquinone, cytochrome aa3, cytochrome b, NADH, cytochrome c, FAD.
To predict:
The sequence of electron carriers such as ubiquinone, cytochrome aa3, cytochrome b, NADH, cytochrome c, and FAD in the membrane of an organism growing aerobically by using the data of Figure 3.10 in the text book.
Concept introduction:
An oxidation is a process in which electrons are removed from a substance whereas, in reduction process, electrons are added to the substance. The combination of these processes is termed as redox (oxidation-reduction) reaction.
Explanation of Solution
The electron transport chain consists of carriers of protons and electrons, which facilitate their transfer from a primary electron donor to a molecule that acts as the terminal acceptor.
The differences in the redox reaction can be identified by comparing the standard reduction potential (E0’). If E0’ of the substance is more negative than the other, it is identified that it undergoes reduction and if E0’ of the substance is more positive, that means it accepts electron and undergoes an oxidation process.
