Total questions: 14
Worksheet time: 5mins
State which cell contains haemoglobin
Thrombocytes (platelets)
Erythrocytes (red blood cells)
Lymphocytes (white blood cells)
Blood Plasma
Which fact is true about Haemoglobin
Helps fight infection
Transports lactic acid
It is a carbohydrate
Each molecule has 4 sections
Where do you have high levels of O2 (pick 2)
blood leaving the lungs
blood leaving the muscle
in the lungs/alveoli
in the veins and venules
What does high affinity mean in relation to haemoglobin
wants to keep hold of O2 molecules
wants to collect lots of CO2
wants to release O2 molecules
neither collects or releases gas
not sure
Why is there a low level of oxygen saturation in the muscle?
because the muscle is relaxed
so that protein is made
the muscle has already used up the O2 to make ATP
so the liver works harder
how many O2 molecules can haemoglobin carry
1
2
3
4
When does the curve shift to the right
when we are relaxed
when we are sat in an ice bath
when we are exercising
when we are eating
There is high affinity in the lungs and low affinity in the muscles
True
False
not sure
When we exercise...
more O2 is made and there is no acidity
more CO2 is made and there is no change in acidity
more CO2 is made and the blood becomes acidic (low pH)
less CO2 is found in the muscle and we breath in less O2
Which of these causes the Bohr shift to the right?
low protein
high O2
high CO2
cold environment
Which of these causes the Bohr shift to the right?
low pH / high acidity
high O2
high carbs
drinking too much water
Which of these causes the Bohr shift to the right?
high O2
increased temperature
low body fat
chocolate cake, lots of chocolate cake
Blood leaving the muscle has (a) levels of CO2
My level of understanding of the O2 dissociation curve
(this is not a question so there is no correct answer)
know it all 100%
know a fair amount 80%
still learning 60%
kind of get some of it 40%
the O2 dissocia....WHAT? 20%
