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.
The sequence of electron carriers in the membrane of an organism growing aerobically and the following electron carriers produced as follows:

- Species Interactions Explain how predators, prey and scavengers interact. Explain whether predators and scavengers are necessary or beneficial for an ecosystem.arrow_forwardmagine that you are conducting research on fruit type and seed dispersal. You submitted a paper to a peer-reviewed journal that addresses the factors that impact fruit type and seed dispersal mechanisms in plants of Central America. The editor of the journal communicates that your paper may be published if you make ‘minor revisions’ to the document. Describe two characteristics that you would expect in seeds that are dispersed by the wind. Contrast this with what you would expect for seeds that are gathered, buried or eaten by animals, and explain why they are different.
