So in undergrad we had to memorize every enzyme and every structure and every name of all the basic pathways. However we never really looked at the whole thing the way we are doing here in med school. Now it is more of a macroscopic view with how the organs play roles and the regulatory steps with each type of metabolite. So I find myself getting confused, and although I did do the pathways in undergrad I have forgotten most of them. Are there any good websites that kind of simplify things in the same fashion that we need to know macroscopically? Thanks!
