Biological Functions of TMs

[306278293]

In lecture, Dr. Lavelle went over a list of transitional metals and their corresponding biological functions (ie: chromium assists insulin in control of blood sugar, cobalt is in vitamin B-12, etc). Are we expected to know these TM functions for the final exam?

In addition, in the same lecture, we went over an example of a porphyrin ligand in a heme complex that when bound to a protein becomes myoglobin, which is allows hemoglobin to bind to 4 O2's, giving it a higher O2 carrying capacity. Are we expected to be able to analyse other biological examples/will we be tested on similar questions and have to know how certain ligands benefits these biological functions?

It is stated in the outline that we must know some biologically important compounds and their relation to ligands (myoglobin hemoglobin, and vitamin B12) so I believe that we should know them. And I think we should know the importance of the transition metals in biological compounds as well :)
