Haemoglobin — cooperativity (3D)

About this app

Four chains that help each other: as oxygen binds, the tetramer switches from the tense T to the relaxed R state, the dimers rotate by about 15° and 2,3-BPG drops out of the cavity. Adjust pO₂, pH (Bohr effect) and BPG, compare the S-shaped binding curve with myoglobin live and read how much O₂ reaches tissue and muscle. Exhibit-ready.
