Original posting as formulated by the Student: I am writing a research proposal in which I am attempted to describe an experimental procedure to isolate olfactory sensory neurons (OSNs) and analyze/compare the amino acid sequences of olfactory receptors expressed by individual OSNs. To do this, I am proposing isolating indivi
1. If your goal is to burn fat, you are better off exercising at lower intensity for longer periods of time, as opposed to short burts of more intense exercise. Looking at Figure 9.27(see attachment) explain why this is true on a cellular level. For number 3 can you check my reasoning here.. 3. In step 6 of citric acid cyc
Contained is a description of the signaling cascade that results from EGF stimulation of the Ras-MAPK pathway in cells. A paragraph description is included that tells in relative detail the various steps, and then a brief numbered list of events is given for quick reference in order to improve understanding of this complicated
What types of exposure and response are associated with DDT in humans?
The four phases of the disposition of a toxic compound to assess its toxicity are absorption through membranes in a system, the distribution throughout the system, the excretion and elimination from the system and lastly, the metabolic fate of the chemical. Using these four phases assess the toxicity on DDT. I would also like to
I am conducting an activity assay to assess the Enzymatic Hydrolysis of 4-Nitrophenyl ?-D-Glucopyranoside by ?-D-Glucosidase. I am happy with the assay, however one of the components is bovine serum albumin ( 0.2% solution in phosphate buffer, to which my enzyme solution is added). I initially assumed that the BSA acted as so
I have to give a 30 minute speech in a couple of weeks about a specific protein. The protein needs to have a crystal structure and have some type of societal impact. I would like a protein that is involved in sports or bodybuilding because that is the subject outside of school that I am most interested in. My question is basical

Complete the table by determining the percentage content of the corresponding complementary bases for each bacterial population. On what assumptions are your calculations made? 2. Describe the relationship between Tm and base
A) Define "transamination" and "oxidative deamination" b) What is the role of the urea cycle, and what are the effects on an individual of a deficiency in one of the required enzymes?
See the attached files. I recently completed a experiment on SDS-Page electrophoresis to identify the molecular weight of my unknown proteins (unknown a and unknown b). I recently received my photograph that I took and I am having a hard time reading it. First off I am having difficult interpreting my photo as I only know that

E) potassium levels. 2. Multiple sclerosis is a result of A) the absence of myelin on nerve cells. B) having excess acetylcholine receptors.
An experiment was performed to determine the effects of an inhibitor on the breakdown of glycogen by an enzyme. In an accompanying experiment, the inhibitor was added to the glycogen-enzyme suspension and reacted using the same experimental conditions. The data obtained from these experiments are in the table Glycogen (mM) 0
1. A drug impairs oxyegen consumption on liver mitochondria at a buffer of 7.4pH, Mg, and adp. It inhibits O2 uptake if isocitrate, 2-ketoglutarate and malate were substrates, but it will NOT is succinate is a substrate. Where's the site of inhibiiton: ATP synthase, malate dehydrogenase, Complex I, II, or III 2. Wha

Please help solve the following dilutions problems with step by step calculations. 1) Prepare 100 mL of 5mM ascorbic acid with 35mM ascorbic acid solution 2) Calculate the final concentration when the 5mM is diluted to 1:500 If you wanted to make 100 mL of a 5mM ascorbic acid solution and you have on hand a 35mM ascorbic
In the movie, Lost in Space, spider-like creatures attacked members of the Robinson family as they explored an abandoned spaceship. Maureen (the mom) scans the creatures and reports that the spiders are silicon-based life-forms. (1) If silicon-based life exists, would it be able to consume carbon-based life, digest it, and u
Please help me with two of these questions. 9. Glucose is experimentally synthesized with C-14 at carbon 1, and used as a substrate for aerobic metabolism. Where is the label at the end of glycolysis? Draw the glycolysis product with the labeled carbon circled or highlighted. Now take that glycolysis product a little farther.
