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
load oxygen faster
show no change
load oxygen slowly
3. One of the factors below will not disturb the “balance” of a chemical reaction:
the presence of phosphorus
temperature
pressure
concentration
4. The concentration of gases is expressed as:
Picograms
Partial concentration
Kilograms
Partial pressure
5. Which of the following functions is performed by the blood?
Prevents sun burn
Prevents bee stings
Makes body hair grow faster
Transfers gases and other substances
6. The pigment found in red blood cells is called:
haemophilia
diploid
haploid
haemoglobin
