Question

auestion 4 Figures of merit (30 pts) oxytocin (OT) vasopressin (VP) mo sensor 1 sensor 2 36.76 x 0.0004 S 0.989 s y 22.47 x+ 0.0001 E R 0.997 10 20 30 10 20 30 Concentration (nM) Concentration (nM) oxytocin (OT) and vasopressin (VP) are both hormones produced in the same part of the brain. Amongst other things, OT is involved in the feeling of love while VP helps you control your pee. Very similar molecules, very different outcomes! We developed two different sensors for the purpose of measuring OT in complex biological samples, and then we made calibration curves with standards of known concentrations of OT (circles, solid trend lines), and VP (triangles, dashed trend lines). In both cases, the equations and r values are given only for the solid trend line. The blank measurement for sensor 1 gav a corrected signal of 0.00 t 110 mV, while the blank measurement for sensor 2 gave a corrected signal of 0.00 t 58 mV. A) Compare and contrast sensor 1 with sensor 2 based on the following figures of merit, and justify your comparison with evidence from the data given above.

Explanation / Answer

Sensor 1 is more specific and less prone to errors than sesor 2. As we can see from calibration curves that calibration curve for sensor 1 forms a straight line with nearly all points lying on or near to it where as such not the case in calibration curve for sensor 2 where firstly some initial values tend to give a straight line but after sometime the values got deviated from uniformity.
