Your friend is trying to learn about how to kill bacteria. She reads the preservatives such as citric acid are added to foods because the acidic environment kills bacteria by denaturing the proteins. She thinks this sounds like a lot of scientific jargon and asks you what it means. How can you explain it in simpler terms?
A. Denaturing their proteins means that the proteins in bacteria are converted into carbohydrates.
B. The acid causes the cells to swell and burst open, also known as denaturation.
C. Denaturing means that the proteins of the bacteria lose their structure and can't function, so the bacteria die.
D. Denaturing refers to the fact that bacterial cells divide too quickly and die.
