  1. 1The Bohr effect shifts the curve of O2 to the [blank_start]left[blank_end].
    1. Aleft
    2. Bright
  2. 2The lungs ahve a large surface area to increase the rate of diffusion. Select anyother properties it has to do so
    1. AMany alveoli
    2. BLots of cappileries suronding the alveoli
    3. CA large wall to help things diffuse across
    4. DA small wall to help things diffuse across
    5. Ea low concentration gradient of O2 in the lungs
    6. FA high concentration gradient of O2 in the lungs
    7. GA low concentration of CO2 in the blood
    8. HA high concentration of CO2 in the blood
  3. 3Foetal haemoglobin curves are shifted to the right.
    1. ARichtig
    2. BFalsch
  4. 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.
    1. Asequence of amino acids
    2. Bamino acids
    3. Cform an alpha helix
    4. Dform a beta bleated sheet
    5. Emore than one polypeptide chain
    6. Fprosthetic group
    7. Gco-enzyme
  5. 5How many polypeptide chains is haemoglobin made of
    1. A1
    2. B2
    3. C3
    4. D4
    5. E5
    6. F8
  6. 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.Bild zu Frage 6
    1. AResidual volme
    2. BTotal lung capcity
    3. CVital Capacity
    4. DTidal volume
    5. EInspiratory reserve volume
    6. FExpiratory reserve volme
  7. 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.
    1. Aexternal intercostal
    2. Binternal intercostal
    3. Ccontract
    4. Drelax
    5. Edown
    6. Fup
    7. Gincreases
    8. HDecreases
    9. Iinto
    10. Jout
