What is the name of the molecule formed when oxygen binds to haemoglobin?

• oxyhaemoglobin

• oxygen-haemoglobin

• carbaminohaemlobin

• oxyglobin

Fetal haemoglobin shifts the oxygen saturation curve in what direction?

• right and down

• left and down

• right and up

• left and up

The ion found in the haem group is what

• Mg²⁺

• O^2-

• Fe²⁺

• Fe³⁺

The main blood vessel responsible for taking oxygenated blood to the body is the

• pulmonary artery

• aorta

• vena cava

• pulmonary veins

Carbon dioxide and water combine to form

• hydrogen carbonate ions

• hydrogen ions

• carbonic acid

• hydrogen bicarbonate

Carbonic acid dissociates to form

• H+ and H₂CO₃^-

• H+

• hydrogen carbonate ions and hydrogen ions

• carbonic acid anhydrase

The Bohr Effect/Shift moves the oxygen saturation curve in what direction

• up and left

• down and right

• down and left

• up and right

This is useful because it means that

• more carbon dioxide can be dissociated

• more oxygen is displaced from the haemoglobin

• less oxygen is displaced from the haemoglobin

• more carbon dioxide can be taken in by the cells

At the highest partial pressures of oxygen, the saturation of oxygen slows down because

• the haemoglobin becomes saturated

• the haemoglobin becomes denatured

• the haemoglobin is too cold

• the oxygen is displaced by carbon dioxide

The blue line on the graph indicates

• the Bohr effect

• regular haemoglobin

• fetal haemoglobin

• haemoglobin during exercise
