Athabasca university in Canada. www.athabascau.ca I did biochem, orgo and a few other courses and did well. And it was/is recognized by all the schools I applied to.
When I surfed the net for my class on UNE's website, I think I also saw a biochem class being offered as an open enrollment. Other than that, I know cell bio is offered at UCSD (if you live in the SD area) this summer.
