Tense to relaxed hemoglobin
WebNational Center for Biotechnology Information Webhemoglobin begins to assume its relaxed state. In other words, binding to some oxygen makes it easier for hemoglobin to bind to more oxygen. a) Tense hemoglobin doesn’t bind oxygen b) Hemoglobin becomes relaxed after avidly. binding some oxygen. Relaxed hemoglobin can better bind more oxygen. Let's take a look at what's happening graphically.
