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 faster
load oxygen slowly
3. The concentration of gases is expressed as:
Kilograms
Picograms
Partial pressure
Partial concentration
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:
haemophilia
diploid
haemoglobin
haploid
