WebCooperativity is a complex subject; one model is the interconversion of the hemoglobin between two states—the T (tense) and the R (relaxed) conformations—of the molecule. The R state has higher affinity for oxygen. WebCompared to myoglobin, hemoglobin has a much more complete. Hemoglobin has a T and R state. In the T (tense) state, or deoxygenated state, the binding sites of hemoglobin are constrained. In the R (relax) state, or oxygenated state, the binding sites are less constrained, making it easier for the hemoglobin subunits to bind to oxygen. There are ...
