Hypoxia is a condition in which tissues of the body are deprived of an adequate oxygen supply. A study was carried out in rats to examine the effects of continuing hypoxia on the structure of the diaphragm, and to determine whether nitric oxide is implicated in adaptation of the diaphragm to hypoxia. The diaphragm helps to supply oxygen to tissues and organs in the body by ventilating the lungs.
A group of 36 adult male rats were kept for 6 weeks in low oxygen while 36 adult male rats were kept in normal oxygen levels.

Outline the effect of hypoxia on body mass and erythrocyte percentage. [1 mark]
31b.
The graph shows the effect of hypoxia on the endurance of rats’ diaphragm muscle after 6 weeks.
Endurance is the change in force measured as a percentage of the initial force.

Using the data in the graph, deduce whether hypoxia increases or decreases the endurance of the rats’ diaphragm muscle. [2 marks]
31c.
Using the data presented in this question, explain the effect of hypoxia on the body. [2 marks]
31d.
The sodium–potassium pump plays a role in muscle activity. Nitric oxide may have a role in the recovery of hypoxic muscles. The production of nitric oxide can be blocked with an inhibitor of the enzyme nitric oxide synthase. The graph shows the concentration of sodium–potassium pumps in the diaphragm of control and hypoxic rats without and with nitric oxide synthase inhibitor.
Analyse the graph to obtain two conclusions about the concentration of sodium–potassium pumps. [2 marks]
31e.
Muscle fibres are stimulated to contract by the binding of acetylcholine to receptors in their membranes and the subsequent depolarization.
Suggest a reason for increasing the concentration of sodium–potassium pumps in the membranes of diaphragm muscle fibres. [1 mark]
31f.
Skeletal muscle contractions can take two different forms: if they are stimulated by a single action potential they take the form of a twitch and if they are stimulated by a series of action potentials the contraction is longer lasting (tetanic). The table shows the effects of hypoxia on the force of twitch and peak tetanic contraction in the diaphragm.
Outline the effect of hypoxia on the force of contraction of the diaphragm. [1 mark]
31g.
Hypoxia caused a 13 % increase in the surface area to volume ratio of the diaphragm. Suggest a reason for this change. [1 mark]
31h.
Using all relevant data in the question, evaluate the effectiveness of the rats’ adaptation to hypoxia. [3 marks]
31i.
Discuss the advantages and disadvantages of using rats as models in this investigation. [2 marks]
