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