A diabetic patient uses a glucose test strip that contains the enzyme glucose oxidase, a peroxidase enzyme, and a colourless chromogen. A droplet of blood is placed on the test strip. After 30 seconds, the strip is inserted into a meter that measures the intensity of the colour produced. Different glucose concentrations produce different colour intensities, as shown in the table.
| Glucose concentration (mmol dm) | Colour intensity (arbitrary units) |
|---|---|
| 2 | 20 |
| 4 | 40 |
| 8 | 80 |
| 16 | 160 |
Explain the principles of how the glucose test strip works and why monitoring blood glucose concentration is important in homeostasis.
