oxygen transport

• when partial pressure of carbon dioxide is high it allows for oxygen to dissociate easily
• the bohr effect is when increased carbon dioxide production leads to a decrease in blood pH as it reacts with water to form carbonic acid. the low pH causes the tertiary structure of haemoglobin to change increasing the dissociation of oxygen
• the further left the curve the higher the haemoglobin affinity for oxygen

  
• the bohr shift can be an increase of CO2 shifting the dissociation curve to the right
• high respiration means the curve will shift to the right
• low oxygen areas mean the curve will shift to the left
