cooperative binding

• what is cooperative binding


  the increase in ease at which haemoglobin binds its second and third oxygen molecules
• what happens when an molecule bonds with a protein


  it will cause a slight change in shape of the protein
• what happens to haemoglobin when oxygen binds to it


  it will cause a slight change in shape of the protein
• during cooperative binding what happens to the shape of the haemoglobin once the first protein has bound to the haemoglobin


  it causes a change in shape that makes the second and third binding site more available
• what will the happen to the haemoglobin affinity during the bounding of the firs oxygen molecule


  it will increase
• describe how the final oxygen binds to the haemoglobin


  there is only one binding site that is available which increases the difficulty of the oxygen binding
• describe the graph of cooperative binding


  it will be a sigmoid curves due to the binding of oxygen being non-linear
• what does a cooperative binding look like

  
• what is meant by the theoretical line on a cooperative binding graph


  the rate of uptake when the pressure is proportional to the concentration of oxygen
