1The Bohr effect shifts the curve of O2 to the [blank_start]left[blank_end].
- Aleft
- Bright
2The lungs ahve a large surface area to increase the rate of diffusion. Select anyother properties it has to do so
- AMany alveoli
- BLots of cappileries suronding the alveoli
- CA large wall to help things diffuse across
- DA small wall to help things diffuse across
- Ea low concentration gradient of O2 in the lungs
- FA high concentration gradient of O2 in the lungs
- GA low concentration of CO2 in the blood
- HA high concentration of CO2 in the blood
3Foetal haemoglobin curves are shifted to the right.
- AVerdadero
- BFalso
4The primary structure of Haemoglobin is the [blank_start]sequence of amino acids[blank_end]. The secondary structure is when it folds to [blank_start]form an alpha helix[blank_end]. The tertiary structure is when it folds even more. The quaternary structure is when there is [blank_start]more than one polypeptide chain[blank_end]. The iron is a [blank_start]prosthetic group[blank_end] to the protien.
- Asequence of amino acids
- Bamino acids
- Cform an alpha helix
- Dform a beta bleated sheet
- Emore than one polypeptide chain
- Fprosthetic group
- Gco-enzyme
5How many polypeptide chains is haemoglobin made of
- A1
- B2
- C3
- D4
- E5
- F8
6Label this diagram with the appropriate volumes. The Y axis is lung volume in litres and the X axis doesn't matter for this question.

- AResidual volme
- BTotal lung capcity
- CVital Capacity
- DTidal volume
- EInspiratory reserve volume
- FExpiratory reserve volme
7During inspiration the [blank_start]external intercostal[blank_end] muscles, [blank_start]contract[blank_end] bringing the ribcage up and outwards. The diaphragm contracts moving [blank_start]down[blank_end]. This [blank_start]increases[blank_end] the thoraic cavity's volume and the lungs expand. This decreases the presure inside the lungs. The air therefore moves [blank_start]into[blank_end] the lungs.
- Aexternal intercostal
- Binternal intercostal
- Ccontract
- Drelax
- Edown
- Fup
- Gincreases
- HDecreases
- Iinto
- Jout
