Homework Answers
Oxyhemoglobin is known as the relaxed state and deoxy hemoglobin is known as the tenae state.
Bohr effect - deoxyhemoglobin is the surronded by the chain of amino acid. Is does not allow the binding of oxygen to metal centre. When first oxygen break the electrostatic aattraction of the amino acid chain than second o2 bind easily to other iron centrre in hemoglobin compartive to the first or third bind vavery easily than the second . So we can say addtion of oxygen to heme group intiated the addtion of other oygen to bind heme group. This this the physiological bhor effcet.
Please do aummit differntnquestion sepratly we supposed to naswer of one question only thankyou have a nice day

How does BPG, or 2,3-biphophoglycerate produce the shift in
the oxygen bunding curves shown? (BPG works to effect the binding
of oxygen to hemoglobin) Circle the correct choice.
a) BPG binds to the R state of hemoglobin tetramer.
b) BPG binds to the T state of hemoglobin tetramer.
c) BPG binds to the heme group, which blocks access to the
oxygen
d) BPG oxidizes the iron (II) in the heme group to the iron
(III), preventing oxygen from binding.

2) We discussed in class how the molecule 2,3-bisphosphoglycerate (BPG) is an inhibitor of hemoglobin (Hb). Answer the following questions about BPG and its regulation of oxygen binding: a) Would BPG have any effect on myoglobin’s ability to bind or release oxygen? If so, describe how BPG would affect myoglobin. If not, why? b) Based on the observation that BPG binds preferentially to partially deoxygenated Hb, briefly explain (1-2 sentences) where BPG is most likely to be most effective on...

Bisphosphoglycerate (BPG) is a byproduct of glycolysis. It can bind to the deoxy state of hemoglobin but not the oxy state. Complete the sentence to explain how you expect BPG to shift the Hb-oxygen binding equilibrium. Addition of BPG will _______ because the system needs to compensate for _______ in _________ due to BPG.

How does the change in pH from 7.2 to 8.2 affect the binding of BPG to the central cavity of Hemoglobin's T state? Is it no effect, increase or decrease binding? Explain why.

The blood parasite Dicrocoelium dendriticum expresses a hemoglobin protein that is similar in sequence to human hemoglobin. D. dendriticum hemoglobin (Dd Hb) binds oxygen with much higher affinity than human with hemoglobin. In contrast to human hemoglobin, research has shown that hemoglobin does not form quarternary structure; it exists only as a monomer in solution. The p50 value for varies widely with pH (Smit, j.et al. (1986). Eur. J. Biochem. 155, 231-237.). a. Do you expect to show cooperative oxygen...
