What is the diffusion gradient, and how is it measured?
What is the diffusion gradient, and how is it measured?
The diffusion gradient is the difference in partial pressure (concentration) from one side of a membrane to another, and it is measured in mmHg.
What is the primary factor that affects the amount of oxygen released from haemoglobin and entering the muscle cell during exercise?
What is the primary factor that affects the amount of oxygen released from haemoglobin and entering the muscle cell during exercise?
The primary factor is the oxygen dissociation process, which is influenced by temperature, pCO2, and pH.
How does the production of lactic acid during exercise affect oxygen dissociation?
How does the production of lactic acid during exercise affect oxygen dissociation?
The production of lactic acid during exercise lowers the pH, which increases oxyhaemoglobin dissociation.
What happens to oxyhaemoglobin dissociation during recovery?
What happens to oxyhaemoglobin dissociation during recovery?

What is the difference in partial pressure of oxygen between the blood and the muscle cell during rest?
How does the increase in temperature during exercise affect oxygen dissociation?
How does the increase in temperature during exercise affect oxygen dissociation?
What is the effect of removing CO2 during recovery on oxyhaemoglobin dissociation?
What is the effect of removing CO2 during recovery on oxyhaemoglobin dissociation?
