- Describe the method employed in the electronic assay for glucose.
- Measure urinary metabolites using Clinistiks and explain the basis of the method.
- Construct a graphical representation of your Glucose Tolerance Test and explain its main features.
- Describe how the Glucose Tolerance Test of a person with diabetes would differ from that of a healthy individual.
- Describe the fate of glucose ingested in the test dose for the Glucose Tolerance Test in both individuals with and without diabetes.

Introductory Video
- What enzyme does our blood glucose sensor use?
- So how does the blood glucose sensor work?
- How does the urine glucose strip work?
- What happens in the oral glucose tolerance test?
n.b. watch video in the lab to watch the test being carried out

Worksheet Questions
- I consumed a known amount of glucose which has a molecular weight of 180g/mole. Calculate how many moles of glucose were consumed (Lucozade = 32.5g glucose, Mars bar = 35g glucose)
- If all of the glucose I consumed remained in the bloodstream, what would its concentration be? (you will need to estimate a value concerning my physiology)
