The Question just states what I have given in terms of coordinates but I do believe it's related to the shape I assume. (Angles, size, ect.)

(a.) Obtain coordinates for: ATP, phosphatidylcholine, B-DNA. G-actin, the lambda represssor/DNA complex or Lac repressor/DNA complex, hemoglobin, myoglobin, HIv gp120, green fluorescent protein (GFP, and RNA polymerase.

(b.) Using a structural viewing code like VMD, create a plot of each of the molecules from part (a)​. Their coordinates can be obtained through their PDB File, a simple google search should help you find them.

(c) By looking at phosphatidylcholine, justify and find the value of the area per lipid.

(d) Phosphoglycerate kinase is a key enzyme in the glycolysis pathway. Obtain the coordinates for bth phosphoglycerate kinase and glucose and examine the relative size of the molecules.

7. Explain how detergents solubilize membrane proteins; give the 2 common detergents.

8. Explain the function and basic structure of the cell cortex.

Swifty Corporation’s high and low level of activity last year was 66000 units of product produced in May and 26000 units produced in November. Machine maintenance costs were $239400 in May and $103400 in November. Using the high-low method, determine an estimate of total maintenance cost for a month in which production is expected to be 49000 units.

THIS QUESTION REQUIRES THE USE OF R STUDIO. ANY ANSWERS GIVEN THAT ARE NOT IN R STUDIO CODE WILL NOT SUFFICE. SOLVING WITHOUT THE USE OF R STUDIO IS NOT ACCEPTABLE.

The previous question was:

Annual salaries for a large company are approximately normally distributed with a mean of 49000 dollars and a standard deviation of 2000 dollars. One manager claims that all of his direct reports are paid "above the 75th percentile" for the company. What is the minimum dollar figure of employees working under this manager?

I used qnorm(o.75, 49000, 2000) to get an answer of $50,348.98 for the minimum dollar figure for employes under that manager.  

The current question:

Part 1: Create a neat, annotated, complete normal density plot representing the second part of the above question with the primary x-axis set to X.

I am struggling with the code for this question.  

Part 2: add a secondary x-axis to the plot from above, showing the Z values that correspond to the x-values of the first axis.  

Please show all code to obtain results.  

You want to maintain pH = 7.0 for an enzyme-catalyzed reaction that will produce hydrogen ions along with the desired product. At equal concentrations, which weak acid, if any, will serve as the better buffer for the reaction: Acid A pKa = 6.5, Acid B pKa = 7.5

a. Acid A

b. both are equally effective

c. water is as good as either of the acids available

d. acid B

*** I get that answer A is correct but Wouldn't B (pKa = 7.5) be better because as more H+ gets released by the reaction the pH would go down closer to 7, while if A was used the pH would fall further away from 7 . Also I'm not sure what is at "equal concentrations" as in the question

An antifreeze protein, with a molecular weight of 17000 Da, was found to be present at a concentration of 10g dm-3 in the serum of an Antarctic fish. calculate the expected depression of the freezing point and compare your result with 1) the observed depression of 0.6K and 2) the depression of 0.0014K observed for 10g dm-3 solution of lysozyme, molecular weight of 14500 Da. for pure water, Lf=6.02kj ml-1 and Tm=273.15 K
