WebHemoglobin 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 … There are two states in the hemoglobin, the T state (the tense state) and the R state (the relaxed state). The T state has less of an affinity for oxygen than the R state. In the concerted mode of cooperativity, the hemoglobin must either be in its T state or R state. In the sequential mode of cooperativity, the conformation … See more Hemoglobin (Haemoglobin in many varieties of English and often abbreviated to 'Hb') is a tetramer consisting of two dimers that bind to oxygen.
