An enzymatic reaction converts starch to simple sugars using a fungal enzyme that is very pH sensitive and works efficiently ?f and only if the pH of the reaction environment is ?.20. Your statistician, Mr. Biswadeep Pai decides to use a pH meter that is known to give normally distributed replicate measurements. Suppose that ?0 independent replicate measurements of pH yield the following values: {?. ?8, ?. ?7, ?. ?6, ?. ?5, ?. ?1, ?. ?7, ?. ??, ?. ?8, ?. ?9, ?. ??}.

(a) What conclusion can Biswadeep draw at the ? = ?. ?0 level of significance?

(b) What conclusion can Biswadeep draw at the ? = ?. ?5 level of significance?

(c) Is "?f and only if" in the above problem statement a typo?

Solutions

Expert Solution

First we need to find the mean and SD of data. Following is the output of descriptive statistics:

Descriptive statistics
X
count 10
mean 8.1850
sample standard deviation 0.0246
sample variance 0.0006
minimum 8.15
maximum 8.22
range 0.07

a)

b)

(c)

No because test is not significant 5% level of significance. So pH level can be 8.20.

You have an enzymatic reaction proceeding at the optimum pH and optimum temperature. You add a competitive inhibitor to the reaction and notice that the reaction slows down. what can you do to speed the reaction up again? Add more inhibitor to speed up the reaction. Add more substrate; it will outcompete the inhibitor and increase the reaction rate. Increase the temperature. Increase the pH.

A simple enzyme reaction can be described by the equation E+SESE+P, where E is the enzyme, S the substrate, P the produce, and ES the enzyme substrate complex. Write a corresponding equation describing the workings of a transport (T) that mediates the transport of a solute (S) down its concentration gradient. What does this equation tell you about the function of a transporter? Why would this equation be an inappropriate choice to represent the function of a channel?
