Question on practice exam

Postby Yiwei Zhou 2I » Fri Dec 08, 2017 11:17 pm

22. A protein like histidine can bind at one site to the heme complex iron to from myoglobin. How many O2 molecules can myoglobin bind? How many myoglobin form a hemoglobin?

Can someone explain this question for me? Thanks so much!

One oxygen molecule binds to each myoglobin.
Four oxygen molecules bind to each hemoglobin thus, I think four myoglobin would make up one hemoglobin. I'm not entirely sure though.

You are absolutely positive, 4 myoglobins DO make up one hemoglobin. This was a medical example that Lavelle shared with us in class.
