I think biochem will be fine to use for fulfulling the bio requirement. Does the biochem class also have a lab component? Keep in mind you need to have 4 semesters of bio related lab classes. These can either be separate lab classes or ones that are taken in conjunction with the lecture.
If you ask UOP, they'll say they're really strict about the requirements, but I don't know if that's really true. My undergrad had a weird track for chemistry, we only had to take one semester gchem, 2 semesters ochem, and one semester biochem to complete the chemistry series. After getting accepted, I asked if I would still have to take that second semester of gchem, even though my school didn't require it. They told me my DAT score was high enough that it didn't matter.
So I guess there's certain ways to skirt around the requirements, but I wouldn't advise it. Give them a call and verify biochem can be used as a bio requirement.
