Homework Answers
Secondary metabolites are the compounds that are produced by bacteria due to enviornmental stress. They do not have a vital role in growth, development, and reproduction lin plants they are synthesized at end or near the stationary phase of growth.
Bacitracin is a secondary metabolites that are formed by bacillus subtilis. It is used as antibiotics. It is synthesized by bacteria as a nonribosomal peptide synthetase that have a role in synthesize peptide.
Hence bacitracin is the antibiotics that is produced by bacteria as a secondary metabolites because it has role in synthesis of peptide.

6. a. Explain why the antibiotics Gramicidin, Nonactin, and Valinomycin are toxic to bacteria. (You will need to do some research since those antibiotics are not described by name in your textbook.) b. Which of the three antibiotics listed in 6a above are less effective at lower temperatures? Explain your answer. 7. Generally speaking, most cells do not have proteins whose sole function is to actively transport water into or out of the cell. Why?

Explain why the overprescription of antibiotics by doctors, or the overuse of everyday soaps containing antibiotics, can be a health risk. O The overuse of antibiotics or antibiotic soaps can be a health risk because the repeated exposure to antibiotics can damage human cells. When antibiotics are overused, the repeated exposure triggers mutations in the bacteria that result in resistance. Resistant bacteria will then survive and multiply, reducing the effectiveness of the antibiotic treatment in the future. When antibiotics are...

Antibiotics has led to development of bacteria resistant to antibiotics. Which led to stronger antibiotics, with the understanding of the theory of evolution from Darwin, particularly natural selection, explain the phenomenon.

Which of the following best describes the significance of the production of antibiotics from soil bacteria in the environment? The production of antibiotics by soil bacteria aids in the absorption of nutrients in the soil. The production of antibiotics by soil bacteria reduces competition by killing microbes competing for the same resources. The production of antibiotics by soil bacteria aids in the reproductive cycle of the organisms that produce the antibiotics. The production of antibiotics by soil bacteria aids in...

Drug Resistant Bacteria There are bacteria that is resistant to many antibiotics which makes it difficult to treat. Look up MRSA, VRE and VRSA and give a short synopsis of each. What can you tell patients to make sure that they will not become resistant to antibiotics?

Question 13 Microbes can become resistant to antibiotics and prevent the antibiotics from damaging them. Why? (Select all that apply) When bacteria reproduce, chance mutations that can protect the bacterium against a particular antibiotic occur. Bacteria reproduce very fast. The antibiotic changes the DNA of the bacterial cells. While most of the bacteria succumb to the antibiotic, the few that survive go on to reproduce and replicate the resistance. In any large population of bacteria, a few cells will be...

5. Beta-lactam antibiotics are the major antibiotics. Where they act? Name two different types of antibiotics which fall in this category. Explain where they resemble and where they differ. 6. Penicillin and Tetracycline; which one is narrow spectrum and which one is broad spectrum and why-explain. 7. There are two types of antibiotics which act on membrane. Name one member of each type. Why one antibiotics of this group exclusive works on fungus/protists and not on bacteria. 8. Many antibiotics...
