Question 4

What is pencellin

Answer 4

Penicillins are used to treat infections caused by bacteria. They work by killing the bacteria or preventing their growth.

Question 5

5 factors for the development of pencillin

Answer 5

1: technology, without developments it would be impossible to mass produce or store the high amounts of pencillin needed during the war

2: Attitudes in society, during WW1 there was lots of urgency for a antibiotic medications

3. Science, scientists with new scientific methods and experimentation could identify the pencillin in cultures and modify it to attack certain bactera.
4. Individuals Chain and Flore built on Earnst’s work on pencellin. All three didn’t take out patents that would make this costly.
5. Instutions, the american government funded the research for a heavy and long time.

Question 6

Why was pencellin important finding for medecine

Answer 6

Becuase normal antispectics could not affect bacterial infections at all.
