Organic chem vs Biochem?

I'm in the process of applying to some schools in Michigan. I only have one chemistry from nursing school (introductory chemistry or something of that sort). I was going to take organic chemistry in the winter, because that's what one of the schools specifically asked for. I was just wondering if biochemistry wouldn't serve me better. I'm thinking not just in terms of getting into school, but actual knowledge gained and applied in grad school.
