How many residues contain sulfur? Identify these amino acids.

Glycine is acetic acid (ethanoic acid) with an amine group attached i.e. 2-amino acetic acid. The pKa of the glycine carboxyl group is 2.34 and the pKa of acetic acid is 4.75.  Briefly explain why there is such a large difference in the pKa values between these two carboxylic acid groups.

The group auditors decide not to assume responsibility for the work of component auditors who audited a wholly owned subsidiary of the group financial statements. The total assets and revenues of the subsidiary represent 27% and 28% of the related group financial statements. If no issues are encountered in either the group auditors’ or component auditors’ examination, what type of opinion should the group auditors issue?

What is the minimum starting O2 rate recommended for both adult and pediatric patients?

These figures show the protein structure of hemocyanin, the copper-containing oxygen transport protein in arthropods, octopuses, and squids. The two figures are of the same protein, one a “front” view and a “back view”- a 180o rotation about the vertical axis. The small diamond-shaped dicopper structure is the in the center. This molecule is responsible for the blue color of the oxygenated blood of these animals. Image Description A 3D representation of a protein structure, displaying its complex folding and various regions. The protein features several alpha helices, depicted as spirals, and beta sheets, depicted as arrows, interconnected by loops. The structure is colored with a gradient from blue (N-terminus) to red (C-terminus), illustrating the flow of the polypeptide chain. This visual highlights the intricate architecture crucial for the protein’s specific function. Referring to the figure, briefly describe the secondary structure of the three-strand flat ribbon structure at the top of this protein. (1pt.) The sequence of the vertical helix on the right-hand side of the first figure is IPELEEHLKEI. Briefly explain why this helix has both a polar and a nonpolar side and which way you would expect to find the nonpolar side facing relative to the rest of the protein’s structure. (2 pts.)

The results of the polyacrylamide gel electrophoresis (SDS-PAGE) for lebecin are shown in the figure to two right-hand lanes. The series of labeled bands on the left-hand side of the gel are known molecular weight markers. Each band in the left-hand lane corresponds to a known protein whose molecular weight shown in units of kD. The middle band, labeled NR, shows the purified protein that was not treated with BME (

Mr. Johnson has many hypopneas and respiratory event-related arousals (RERAs) and continuses to snore at a CPAP setting of 16cm H2O.  He wakes up again and describes that he cannot tolerate the high pressures.  He asks Amy to stop the sleep study.  What should the technologist do? 

A patient’s bed partner states the patient seems to be “beating on the pillow” during the night. Which of the following would be most appropriate to include during the overnight polysomnography?

Which of the following parameters MUST be monitored to determine PAP therapy efficacy?

Audit planning requires that the auditor consider possible inventory errors or frauds that might occur that could affect the financial statements. For each of the types of inventory errors listed in the following table, indicate what would be the possible effect in the inventory and cost of sales accounts: overstated (O), understated (U), or no effect (NE).   Type O for overstated, U for understated, or NE for no effect. If you type anything other than O, E, or NE your answer will be marked as incorrect. Inventory Error Effect on Inventory Effect on Cost of Sale Unrecorded receipt of inventory December sales recorded in January December purchase recorded in January Inventory omitted during physical count Consigned out inventory omitted during physical count Unrecorded shipment of inventory
