Biological Importance

Postby elizabethrojas1G » Tue Nov 17, 2015 2:34 am

I'm having a bit of trouble understanding the reaction of hemoglobin and oxygen in the process of homeostasis, can somebody explain it thoroughly for me please? Hb(aq) + O2(aq) <--> HbO2(aq)
Also, can you compare this to myoglobin and explain what the relationship between the two is?

the equation is basically showing the transport of oxygen by hemoglobin
hemoglobin is made up of 4 proteins, each with a heme complex(tetradentate ligand + Fe in the middle). Oxygen molecule is transferred by binding to and then dissociating from the transition metal Fe, which is also bonded to the tetardentate.

Hemoglobin transfer oxygen in blood and myoglobin is in muscle cells
Hemoglobin has 4 myoglobin like molecules, meaning that one molecule can bind to 4 oxygen molecules, while myoglobin can only bind to 1.
They both contain the porphyrin ring ligand, work with transition metal Iron and transport oxygen.
