No. Some places will allow biochem in place of organic II, but not gen chem. Florida schools, or at least the ones I applied to, require both organics in addition to 4 credits of biochem. There is nothing similar to gen chem with biochem. I'm in a 4 credit biochem class now and it is my personal hell. It relates more to rote memorization than anything else. Remember all that stuff that you glazed over in bio 1, such as Krebs and what not? We go into every mind numbing detail and memorize every structure, enzyme and cofactor for all of that. My class is focused on "human" biochem, yet many others won't be. Suck it up and take general chemistry II. This class makes me laugh at the times I complained about gen chem or organic. The mcat will also have more general chemistry on there than biochem.
I'm extra bitter now because I've only studied 30 hours or so for this exam and don't even come close to knowing the material to the extent I should.
