Oxygen and carbon dioxide transport in mammalian blood relies on the biochemical properties of haemoglobin and its derived species. Three of these species are listed in the table below.
Place ticks (✓\checkmark✓) in the correct boxes to indicate which properties and features are true for each species.
| Species | Contains oxygen molecules bound to iron (Fe2+\text{Fe}^{2+}Fe2+) ions | Formed when a gas or ion binds directly to the globin polypeptide chains | Acts as a buffer to prevent a decrease in the pH of the erythrocyte cytoplasm | Its formation is promoted in regions of high metabolic activity |
|---|---|---|---|---|
| Oxyhaemoglobin | ||||
| Carbaminohaemoglobin | ||||
| Haemoglobinic acid |
