Hemoglobin exists in two states: the T (deoxygenated-tense) state and the R (oxygenated-relaxed) state. The two states differ in their affinity to bind oxygen. proofpoint cyber awareness trainingHemoglobin exists in two forms, a taut (tense) form (T) and a relaxed form (R). Various factors such as low pH, high CO 2 and high 2,3 BPG at the level of the tissues favor the taut form, which has low oxygen affinity and releases oxygen in the tissues.
