hyperbolic binding curve differs from a sigmoidal binding curve in that the hyperbolic curveAnswers: A. has a single constant affinity for oxygen binding.B. binds more oxygen after the initial proteins first bind oxygen.C. shows cooperativity.D. binds up to four molecules of oxygen.E. All of the above

The hemoglobin-oxygen (Hb-O2) dissociation curve at high altitude (red) has a distinct shape from that at atmospheric pressure (black). Which of the following best explains the sigmoidal shape of the curves?  A.Dissolved oxygen in the blood serves to increase pH.B.The primary structure of Hb is changed by oxygen binding.C.Dissolved oxygen forms a chain of atoms that binds more easily to Hb.D.Homotropic regulation by oxygen occurs.

describe the major components of the pathway of glycolysis and its control through its three major enzymes including understanding enzyme function that demonstrate a hyperbolic vs sigmoid curve.

Which of the following does not shift the oxy-haemoglobin dissociation curve to the right?1. increased pH2. increased carbon dioxide3. increased temperature4. increased 2,3 -DPG

a. The concerted model can explain well the cooperative binding of oxygen to hemoglobin. Drawthis model below, with a subunit of hemoglobin in the T state as a square and a subunit in theR state as a circle. Include equilibrium arrows between the different states.b. Describe how this model does explain the cooperative binding interaction betweenhemoglobin and oxygen. (in your answer you must make clear why this interaction iscooperative, it is not needed to support this with structural details, e.g. hydrogen bondsspecific conformational changes etc, just use the info in the model)

2.Which molecule binds the active site of the enzyme?
