A. reduction in the dosage of drugs

B. change in the timing of medication administration

C. Increased dose of prescribed drugs

D. All prescribed drugs must be given by intramuscular injection

Using biochemistry concepts and connections by Appling answer the following:

Answer 1 or 2

1. Several of the pathways in this module contain examples of enzymes with opposite function controlled through reciprocal allosteric regulation. Pick an example from one of the pathways studied (pentose phosphate pathway, glycolytic pathway) and describe how a specific allosteric effector affects two different enzymes in an opposing manner. Your answer should also include an explanation of why this reciprocal regulation is important for the control of both pathways.

2. Pick one enzyme that is regulated by both an allosteric effector and covalent modification. The effect of the two regulators can be the same or different (for example, both can activate/inhibit the enzyme or one can activate while the other inhibits). Explain the conditions that lead to each type of regulation, how the effect of each makes metabolic sense in the context of the larger pathway, and why both types of regulation are needed for this particular enzyme.

1. Compare and contrast the diseases epidermolysis bullosa simplex (EBS) and sickle cell anemia. Include molecular level details for one similarity and three differences.

The data table below represents offspring generated through a 3 point mapping cross in Drosophila. Use the table to answer the following questions:

a. What was the parental cross (parental genotypes)?

b. Fill in which phenotype represents the different classes (NCO, DCO, SCOs).

c. What is the relative order of the genes?

d. What is the map distance (centimorgans) between the first and second genes (region I)?

e. What is the map distance (centimorgans) between the second and third genes (region II)?

f. What is the coefficient of coincidence (C) and degree of interference (I)? What do these values mean?

diffusion experiment: my experiment was to cut an agar cube into 64 pieces and place it into different volumes of water. we placed it into 200 mL ( slope of 24) , 600 mL (slope of 12) , and 800 mL (slope of 8). The slope is from the graph, its rate of diffusion graph from each volume.

a. which had the largest affect on the rate of diffusion?

b) Based on your experiments, discuss at least two adaptations that affect diffusion in living organisms (physiological, structural, or behavioral features that evolved due to a selective advantage that was based on diffusion) . Do these match with the factors you identified in a?

Suppose that you isolated an enveloped helical RNA virus. Purified RNA from this virus is capable of supporting translation in a rabbit reticulocyte cellfree translation system or in any other such system Further analysis indicates that this virus replication is inhibited if infected cells are incubated with protease inhibitor such as trypsin inhibitor.

Based on this information, discuss the mechanism by which this virus replicates its genome in infected susceptible, permissive cells.

The effect of BSA on the attachment of NIH-3T3 to cell culture plates. BSA should have interfered with cell attachment.

Suggest a mechanism that might account for this.

Design a serial dilution to achieve a final dilution of 10^-4 such that there will be enough solution remaining in each dilution to use for an assay that requires 100 mL of sample in triplicate. Remember that better accuracy is obtained with relatively large dilutions if the total dilution is made from a series of smaller dilutions rather than one large dilution.

Consider the various components we have been discussion from basic insect form and function, diversity, trophic interactions, symbiosis, to the complexities of ecological interactions, and the foundations from your other courses such as microbiology and parasitology- to generate your own hypothetical vector. Select your pathogen, select your insect or arachnid taxon (with justification), potential host(s), and create a vector that is effective at infectious disease spread. Give it a COOL name.

1. Which of the following are TRUE about sperm?

Select one or more:

a. Hyaluronidase is the enzyme involved in dissolving the protective coating around the unfertilized ovum.

b. The first sperm cell to reach the egg successfully fertilizes that cell.

c. Sperm cells have half the number of chromosomes as a spermatagoium and are about the same size.

d. Sperm cell capacitation, which occurs after ejaculation, is required for sperm cells to be active.

e. Mitochodria are located in the mid piece of the tail below the head.

f. The head of the sperm contains the DNA from the father.

g. The acrosome is located at the base of the sperm cell's tail.
