Johnson Spectrophotometer; the finding of protein concentration of an unknown sample of BSA‚ and by using the standard curve. Abstract A spectrophotometer’s purpose is to use colors of the light spectrum to determine the concentration of light absorbing molecules in a solution. (p.59) In this particular lab‚ our mission was to determine the protein concentration and the standard curve of the unknown sample of BSA. This‚ by preparing five dilutions of the unknown solution of BSA together with

Review Sheet Results (1) 1. List the hematocrits for the healthy male (sample 1) and female (sample 2) living in Boston (at sea level) and indicate whether they are normal or whether they indicate anemia or polycythemia. 1. The hematocrit value for the healthy male: 48 2. The hematocrit value for the healthy female: 44 Both values are normal because they are between the normal ranges: for males between 42-52% and for females between 42-47%. 2. Describe the difference between the hematocrits

What is the Philips Curve? Explain why critics believe the relationship no longer holds. Different macroeconomic policies can be implemented in order to achieve government’s main objectives of full employment and stable economy through low inflation. Philips Curve can be use as a tool to explain the trade-off between these two objectives. This essay will first explain the Philips Curve and its relation to inflation and unemployment. Then‚ the breakdown of Philips Curve will be analysed

How does this tracing compare to the one that was generated at the threshold voltage? At 3.5V the high & low peaks were just slightly above and below respectively the tracing that occurred at 3.0V 4. What reason can you give for the change? An increase in the voltage can cause an increase in the peaks

Sugar Metabolism Title: The effectiveness of glucose and fructose metabolism in individuals of resting and exercising observed through blood glucose concentration. Aim: To study the mechanisms of the body involved in absorbing and metabolizing sugar in the form of glucose and fructose and examine the effect of exercise on the rate of removal of glucose from the bloodstream. Introduction: The blood glucose concentration in the blood is interceded by the human body via negative feedback mechanism
