Protein (albumin) in the urine can be a sign of kidney disease. A colorimetric method can be used to determine the protein concentration in a urine sample by first creating a calibration curve of known protein concentrations.
To produce this calibration curve, you are provided with:
Use the information provided to describe how you could produce a calibration curve for protein concentration. Do not include details on the use of glassware in your answer.
Describe how you would determine the concentration of protein in a patient's urine sample using your calibration curve.
Practise AQA A Level Biology Proteins with exam-style questions for A Level Biology. 22 questions covering General properties of proteins and Many proteins are enzymes, matched to the AQA A Level Biology (7402) specification and written in Paper 1, Paper 2 and Paper 3 style. Every question includes a full worked solution and mark scheme, so you can see where marks are awarded rather than just whether you got the answer right.
