Transport of oxygen in the blood

1. Le Chatelier’s Principle relates to:
a factor that affects blood groups
factors that affect the dissociation of white blood cells
factors that affect the balance between red and white blood cells
factors that affect the oxygen dissociation curve of haemoglobin
2. The concentration of gases is expressed as:
Picograms
Partial pressure
Partial concentration
Kilograms
3. When carbon dioxide tension is high, the haemoglobin will:
show no change
not attract any oxygen molecules
load oxygen slowly
load oxygen faster
4. One of the factors below will not disturb the “balance” of a chemical reaction:
concentration
pressure
temperature
the presence of phosphorus
5. Which of the following functions is performed by the blood?
Prevents sun burn
Transfers gases and other substances
Makes body hair grow faster
Prevents bee stings
6. The pigment found in red blood cells is called:
