Describe the path taken by carbon dioxide molecules from respiring cells to red blood cells.
State three differences between the blood at Y and the blood at X apart from carbon dioxide concentration.
Identify the enzyme that catalyses this reaction: $\text{CO}_2 + \text{H}_2\text{O} \rightarrow \text{H}_2\text{CO}_3 \rightarrow \text{H}^+ + \text{HCO}_3^-.$
Explain why this reaction is important in the transport of carbon dioxide.
State the percentage saturation of haemoglobin with oxygen at an oxygen partial pressure of $5\,\text{kPa}$ when the carbon dioxide partial pressure is: $1.0\,\text{kPa}$ $1.5\,\text{kPa}$.
The percentage saturation of haemoglobin with oxygen falls as the partial pressure of carbon dioxide rises. Explain why.
Name the effect of a higher carbon dioxide concentration on the oxygen dissociation curve.
Explain why the effect of carbon dioxide on haemoglobin shown in Fig. 2.2 is important.
Name the effect of a higher carbon dioxide concentration on the oxygen dissociation curve.
Explain why the effect of carbon dioxide on haemoglobin shown in Fig. 2.2 is important.
