Transport of oxygen in the blood

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