Answer:
Components of the electron transport chain (ordered by electronegativity from least electronegative to most electronegative):
NADH dehydrogenase >> Coenzyme Q >> Cytochrome b-c1 complex >> Cytochrome c >> Cytochrome oxidase complex > O2
Explanation:
The electron transport chain transfers electrons from donors to acceptors via redox reactions (i.e., where reduction and oxidation occur together), and couples the transfer of electrons with proton transfer (H+ ions) across the membrane. In the electron transport chain, the electrons are transferred from NADH dehydrogenase NADH to oxygen (O2) through a series of transmembrane complexes: NADH-Q oxidoreductase, Q-cytochrome c oxidoreductase and cytochrome c oxidase. In the first place, the reduced form of coenzyme Q (ubiquinone) transports the electrons from the NADH-Q oxidoreductase to the Q-cytochrome c oxidoreductase complex (Cytochrome b-c1 complex). Second, the cytochrome c transports the electrons from this complex (i.e., Cytochrome b-c1 complex) to the Cytochrome oxidase complex, this being the last component in the electron transport chain that is responsible to catalyze the reduction of O2.
Synthesis releases energy because the molecules bond to form a stable configuration and therefore give up energy. The bonded molecules have a lower energy level than free molecules and are held in the new bond.
Answer:
What the doctor <u>should</u> recommend is: washing hands frequently, especially after touching a lesion
, taking acyclovir for a 6- to 12-month period
, and always wearing a condom when having sexual intercourse. What he <u>shouldn't</u> recommend is taking penicillin daily for the next year.
Explanation:
Genital Herpes is a viral disease that is frequently transmitted through sexual intercourse and causes infected sores, ulcers and cuts.
While the treatment for herpes can reduce the symptoms, the virus remains latent in the body and will most likely re-appear to cause the same symptoms.
Even when inactive, the virus can be transmitted, so the only way to prevent the spread of herpes is by using condoms or dental dams when engaging in sexual relationships.
To treat herpes, the best option is acyclovir -an antiviral-.
Penicillin WOULD NOT WORK because it is an antibiotic and thus it only kills bacteria (not viruses).
Answer: A) Evolution or B) Natural Selection
Explanation: The fur of these bunnies change color with the seasons in order to better blend into their environment. This is an example of a species evolving to better survive!
However, this could also happen as a result of natural selection. Those who were able to better survive would pass on their genes for fur that changes with the seasons.
