What is the fancy name for red blood cells?
How are red blood cells adapted to their function?
Why do red blood cells have no nucleus, no mitochondria, and no endoplasmic reticulum?
What is the fancy name for oxygen leaving the haemoglobin?
What type of protein is haemoglobin?
How many polypeptide chains does haemoglobin have?
What allows haemoglobin to attract oxygen?
What is meant by the symbol "pO2"?
Is there a high or low partial pressure of oxygen at respiring tissue?
What is oxygen affinity?
What happens to the oxygen affinity of partial pressure of oxygen increases?
Where does fetal blood obtain all its oxygen? Explain how this happens
Does fetal haemoglobin have stronger, weaker or equal affinity for oxygen?
True or false - Fetal blood can obtain oxygen at a lower pO2 due to its greater affinity for O2
What are the three ways CO2 is transported in the blood?
Inside the red blood cell, a reaction takes place with CO2 and H20, what is the product?
CO2 + H2O ---- ???
The carbonic acid inside the red blood cells dissociates. What is produced?
H2CO3 ----- ?? + ??
What happens to the H+ ions?
What happens to the hydrogen carbonate ions?
What is the bohr effect?
If a tissue has an increased concentration of CO2, what effect will it have on the curves in the bohr shift graph?
Why do we need the bohr shift?
