6. Where are oxygen molecules taken up by the haem group?
- In the tissue fluid
- In the plasma
- In the erythrocytes
- In the white blood cells
7. What is oxygen tension/partial pressure?
- The amount of oxygen in the tissue surrounding the erythrocytes
- The amount of oxygen in the blood
- The amount of oxygen in the tissue fluid
- The amount of oxygen in the blood plasma
8. What can be found in the haem groups?
- A single Fe2+ atom
- Two Fe2+ atoms
- A single Na3+ atom
- Two Na3+ atoms
9. Why is confirmational change necessary?
- All the other molecules will find it easier to associate with the haem groups
- It prevents extra molecules from associating with the haem groups
- The next two molecules will find it easier to associate with the haem groups
- The next molecule will find it easier to associate with the haem groups
10. What substance is produced when oxygen binds with haemoglobin?
- Plasma
- Red blood cells
- Oxyhaemoglobin
- Haemoxyglobin
11. What are erythrocytes?
- Proteins found in tissue fluid
- Red blood cells
- Plasma molecules
- White blood cells
12. How many subunits, each containing a polypepticle chain and a haem group, does haemoglobin have?
13. How is partial pressure measured?
- mPa (milipascals)
- kPa (kilo Pascals)
- Pa (Pascals)
- µPa (micropascals)
14. What is confirmational change?
- When the shape of the haemoglobin changes once the first oxygen molecule has associated
- When the shape of the haemoglobin changes in order to encourage oxygen molecules to associate with it
- When the shape of the haemoglobin changes due to a change in the pO2
- When the shape of the haemoglobin changes.
