Question 1

How does nickel work in the human body?

Accepted Answer

​Grading rubric - answer should include the following items:
Research has not been able to define a specific role for nickel in the human body.It is possible that it may be involved directly in the activity of cyclic nucleotide-gated (CNG)channels and/or with guanylate cyclase activity,which potentiates the action of CNG channels.These channels play a role in renal function and may be found in several other organ systems including the central nervous system,reproductive system and urogenital system.
