Introduction:
Antibiotics are sometimes naturally formed chemicals which are released by soil
Answer to Problem 1MCQ
Correct answer:
A compound synthesized by bacteria or fungi that destroys or inhibits the growth of other microbes is an antibiotic. Therefore, option (b) is correct.
Option (b) is given as “antibiotic”.
Explanation of Solution
Justify reasons for the correct statement:
Antibiotics can be produced only by a living organism such as bacteria. Antibiotics can be generated either alone or by different groups of microorganisms such as bacteria, actinomycetes,and fungi. More than thirty antibiotics have been isolated from those groups. Microbes that can produce antibiotics are useful for the prevention and treatment of many diseases including bacterial and fungal disease. For example, penicillin and tetracycline.
Hence, option (b) is correct.
Justify reasons for the incorrect statements:
Option (a) is given as “synthetic drug”.
Drugs that are synthesized in the laboratory by mimic the action of natural compounds by
Option (c) is given as “interferon”.
Interferon, a human-based compound that is a glycoprotein. It is produced by leukocytes and fibroblasts in response to many immune responses. Hence, it is a wrong answer.
Option (d) is given as “competitive inhibitor”.
A form of enzyme inhibition that contains the binding of an inhibitor that preventsthe binding of the target molecule of the enzyme is termed as a competitive inhibitor. Hence, it is a wrong answer.
Hence, options (a),(c), and(d) are incorrect.
Antibiotics eradicate the bacteria that are susceptible to departing from the resistant
