The average biochemistry major doesn’t really use much anatomy, so it’s not going to significantly help you with your major if that’s what you’re asking. At best, I forsee it helping you with the cardiology or muscle section in General/Introductory Biology. However, it’s definitely not going to be usefull in P-Chem, O-Chem, and Gen-Chem, and it probably won’t be that useful in many of your upper-division Biology courses (Unless, of course, you elect to take Anatomy in college). To be honest, a biochemist focuses a lot more on enzymes, structural proteins, DNA/RNA, etc. than they do on basic human anatomy. These subjects might be covered in an Anatomy course, but they’re certainly not the focus.

In my own experience, I was a Biology major in college and never even considered taking Anatomy. I’m not even entirely sure if my college offered it. I ended up taking Physiology, which I think is very interesting and might end up being more useful in your studies. One of my best friends in college was a Biochem guy, and I’m sure he also didn’t take anatomy. His major essentially had him take most of the classes I took with some extra chemsitry added on.

Thus, must you take Anatomy to do well in college? No. Should you take it if it interests you and you feel you will learn something useful and practical? Yes. Good luck!
