Question
Substances which are obtained from micro organisms but
used to destroy micro organisms areSolution
An antibiotic is a chemical substance, produced by micro-organisms, which has the capacity to inhibit the growth of and even to destroy bacteria and other micro-organisms. Alexander Fleming derived the first antibiotic, Penicillin, in 1928 from a fungi called Penicillium. Antigens are any substance that causes the body to make an immune response against that substance. Antigens include toxins, chemicals, bacteria, viruses, or other substances that come from outside the body. Antibodies are proteins that protect when an unwanted substance enters the body. Produced by one's immune system, antibodies bind to these unwanted substances in order to eliminate them from the system. Another word for antibody is immunoglobulin. An antiseptic is a substance that stops or slows down the growth of microorganisms. They're frequently used in hospitals and other medical settings to reduce the risk of infection during surgery and other procedures.
