This blog is intended to extend your knowledge on the effects of DDT exposure on the human cell. The following link leads to a site that I found very helpful in my studies: http://www.chem.duke.edu/~jds/cruise_chem/pest/ddtup.html.
1. How does DDT get into the cells and why does this pose a threat?
2. What is the importance of Potassium and Sodium inside nerve cells?
3. Why is the leaking of Sodium and Potassium dangerous?

1. DDT is fat soluble,so it dissolves into the plasma membrane. DDT opens up the membrane too much and causes the cell to leak, posing a threat to other cells and the rest of the body.
ReplyDelete2. Sodium and Potassium allow the nerve cells to send and recieve their electrical impulses.
3. Without Na and K inside and outside of the cell, the nerve can no longer fire its impulses. This leads to uncontrollable muscle movements and eventually death.

ReplyDelete1. ddt poses a threat because it opens up the cell membrane but it opens it up to much and it leaks
ReplyDelete2. sodium and potassium help determine when the cell shoots out signals
3. without sodium amd potassium the neve cell could not fire off signals and the body would not function right
1. DDT opens up the plasma membrane to make room for itself, but it opens up too much and makes the cell to leak which can result in paralysis.
ReplyDelete2.sodium and potassium enable the cell to communitcate with other cells by shooting out signals.
3.If all the potassium and sodium leak out the nerve cell won't be able to send out signals.
