The bacterial enzyme streptokinase is used to digest fibrin in patients with atherosclerosis. Why doesn't the injection of streptokinase cause a streptococcal infection?
2- How do we know that streptokinase will break down fibrin and not functional tissue?
3- bromouracil is used as an anti cancer drug it is mistaken for thymine by cellular enzymes during DNA replication, name the enzyme site the nucleoside analog is probably binding.
4- Is glucose completely broken down in respiration or fermentation?
5- How does aerobic and anaerobic respiration differ?

Why is a V vs S plot often inadequate for determining enzyme kinetic constants, and how do various alternate plotting methods allow these values to be determined more adequately? Give examples of alternate methods of kinetic analysis and their utility.
The V vs S plot is inadequate because it makes the assumption that it’s only for a single subunit and substrate. The line on the graph usually represents a line that best fits the data and are not completely accurate. This only measures free enzymes or unstable enzyme substrate complex. An alternate method

We consider a population of cars from a given model year. A sample of 24 such cars
has been recently sold. The sale price as a function of the age of the car is in the Excel
file S4.XLSX (Car) in the Excel directory.
a. Try a linear regression and an exponential (non-linear) regression with Excel to
fit these data. Comment your results.
b. Which regression model seems to fit the data better and why?
c. Run the LINEST function in Excel. Provide the result table.
