Adaptations of haemoglobin HL (2025)
Haemoglobin is specifically adapted for the transport of oxygen. Here we explore how this molecule binds to oxygen and how high levels of carbon dioxide can cause an increase the oxygen dissociation in places where tissues respire most. The affinity of haemoglobin for oxygen at different concentrations is then considered by analysing oxygen-dissociation curves. Which type of molecule is haemoglobin? How can you tell...
