It depends what you want to do. A lot of exciting research is going on in the areas of physical biochemistry/biophysics and many cool tools in biochemistry rely on basic principles of physics (e.g. light microscopy, optical tweezers, x-ray crystallography, NMR, electron microscopy, atomic force microscopy, etc.).
That said, I went through an undergrad biochemistry degree taking only the 1st year freshman physics courses. I did, however, learn most of my physics-related info from physical chemistry courses.
I would recommend definitely taking at least the freshman introductory physics courses, as knowing the fundamentals of physics will be important. Anything afterward depends on your own interest in physics (although I would also recommend taking thermodynamics and other physical chemistry courses through the chemistry department).
