Figure 3: ● ● ● ● ● ● KDa ● 97.4 66.2 45.0 ● 31.0- 21.5 14.4 S-1 p-1 S-2 2-0 This figure was generated by centrifuging a pura sample of protein, removing the supernatant, and resuspending the pellet in the same volume as the supernatant to allow direct comparison. The supernatant and pellet samples were then prepared for SDS-PAGE identically and run via normal SDS-PAGE procedures. In the figure, "s" means supernatant and "p" means pellet. The text or number after the dash represents a different condition. For example, s-1 and p-1 are the supernatant and pellet samples under condition 1. It is not shown, but under wild-type conditions, essentially all of the protein is found in the supernatant. S-3 ● What does the intensity of each band represent? ● Would you find soluble protein in the supernatant or pellet? Why? Would you find aggregated protein in the supernatant or pellet? Why? For each condition (there are 5 different conditions), is there a higher percentage of the total protein…
In the disease familial hypercholesterolemia (inherited tendency for high blood LDL cholesterol levels), the protein that helps clear cholesterol from the blood (called the LDL receptor) has a single amino acid that is different from the normal protein. This amino acid change greatly reduces the ability to clear cholesterol from the blood, resulting in high cholesterol levels and the risk of heart attack.Which of the following are different (compared to normal) in the person suffering from familial hypercholesterolemia? __The sequence of the mRNA that encodes for the LDL receptor. __The DNA sequence of the gene for the LDL receptor. __The presence of the gene for the LDL receptor. __The amino acid sequence of the LDL receptor.

(6) The detection of a specific sugar, such as glucose, is not possible via a simple reducing sugar assay (such as the one you described above) due to the lack of specificity of the method. How do commercial glucose test strips detect glucose specifically? What signal is most often observed using the hand-held glucose monitor? (7) With the growing epidemic of obesity and diabetes due to diet and modern lifestyle, the chemical/food industry has been under increasing pressure to produce artificial sweeteners. Identify two major artificial sweeteners that are now ubiquitous in processed low calorie foods. One is derived from the chemical (synthetic) modification of a small dipeptide, and the other from the disaccharide sucrose. Please draw the chemical structures of these artificial sweeteners and list at least 5 commercial foods in which each can be found.

Amoeboid cells that migrate through our tissues, such as the class of white blood cells known as neutrophils, often do so in a directed manner, triggered, for instance, by chemical signals released by pathogens such as bacteria. Directed migration in response to a chemical stimulus is known as chemotaxis. Part of an efficient chemotactic response is the ability of cells to polarize. As is the case with our structurally-polar polymers like F-actin or microtubules, polarization here refers to an asymmetry in the cells, rather than an electrical charge. In this case, it involves one part of the cell becoming the “front” (or leading edge) and another the rear. In a well-polarized, migrating cell, it’s been observed that an active form of Rac (which, in turn, can activate ARP 2/3) is concentrated towards the front of the cell, whereas an active form of Rho (which, in turn, can activate formin, inhibit cofilin/ADP, and activate myosin II) is found toward the rear of the cell. Based on your…

An experiment was carried out to measure the reaction rate of hydrolysis of acetylcholme (substrate) with serum enzymes (Eadie, 1949). In the experiment, two experiments were conducted, namely experiment 1 without using a prostigmine inhibitor and experiment 2 using a prostigmine inhibitor at 1.5 x 10^-7 mol/l. the data obtained are: a. Is prostigmine competitive or noncompetitive inhibitor? b. determine the value of km and rmax for the two experiments, compare

https://journals.lww.com/acsm-essr/Pages/issuelist.aspx You will need to access the journal website and look for an article using any topic covered in chapters 4,5, 6, or 7. For example, you can use "hormones" and "exercise" as search terms related to chapter 4, or "lactate" and "fatigue" for chapter 5, etc. You need to find a topic with one chapter in mind, though you might find concepts that are addressed by multiple chapters (which is entirely fine). You should be able to find a list of articles- browse the titles, taking note of articles you might find interesting-make sure that they are "free" articles since since the more recent articles will require a fee. When you open the link to a article, look for the title (w/authors), and an abstract that summarizes the results. A little below the abstract is a box with the articles "key points". You will need to post the following: 1. Title of the article w/ authors 2. Article summary- You can just paste the abstract,…
