If you go for Biochemistry then you may have to study a course named Quantum Mechanics which is a topic of Modern Physics as well as Biotechnology will also have some courses which will require physics. If you don't like physics then also this courses will not irritate you that much as compared to Mechanics or EMT. So you can take this and with time you will get the facts clear. Note if you have good mathematical background then Quantum Mechanics will feel you more like mathematics than physics. So no need to worry! Keep studying.

I hope this answer helps. All the very best for your future endeavors!
