***Please copy the questions from the “A Poisoning” case study, answer the questions using a different color font or print. Answer the questions using the vocabulary you learned in chapter 4. This vocabulary is also found in the video.

Video link:

  1. Out of what material are cell membranes made?
  2. Describe why methylmercury and dimethylmercury are far more toxic than elemental mercury?
  3. Does dimethylmercury enter the body by active or passive diffusion? Which type of active or passive diffusion? Would it be facilitated or simple?
  4. What kind of gloves are now required when handling dimethylmercury? Why do you think they are made of two different material rather than just double gloving? Hint: It relates to the same principles for #1 & 2, but with gloves rather than the body.
  5. Testosterone and estrogen are available as patches. What does this tell you about these hormones?
  6. In general, does it make sense to deliver water soluble drugs via transdermal patches? Why or why not?

ALSO: Please complete the Endocrine Lab document attached with this post! Thanks
