Which of the following would move the farthest on a protein gel?   A. cyclin dependent kinase (34 kDa)     B. insulin receptor (156 kDa)     C. phosphofructokinase (85 kDa)     D. sodium-potassium pump (100 kDa)

a. integral memebrane protein that crosses membrane multiple time b. lipid-linked membrane proteins c. peripheral memebrane protein d. integral memebrane protein that crosses membrane ince

You are designing a medical device to collect Carcinoembryonic Antigen (CEA, MW = 180,000 g mol^-1), a tumor marker, from patients in order to create a personalized cancer vaccine. In this medical device, the cellular components of the blood are removed from the plasma. The plasma then flows into an extraction chamber. Within this chamber, the fluid flow divides into 48,000 10-cm long tubes with an inside diameter of 175 um. The surface of each tube is coated with a material that very rapidly adsorbs CEA. Plasma containing 6.1 ug m1^-1 of CEA flows into the chamber at 125 ml min^-1. Assume that the fluids are at body temperature (37°C). The viscosity and density of water at 37°C are 0.691 cP and 0.993 g/ cm^3, respectively. The diffusivity of CEA inside the extraction chamber is 6.1 x 10^-6 cm^2/s and the mass transfer coefficient for CEA inside the device is: k = 1.25 x 10^-5 cm s^-1. •If you run the extraction for 1 hour and extract 31.7 mg of CEA, what must be the concentration of…

There are two types of antifolate drugs (primarily DHFR inhibitors): Classical antifolates and Non-classical antifolates. How do these two types of antifolates differ from each other? a.Mode of transport into the cell b.Natural vs synthetic c.Function

You have made several mutations in the coding region of the gene coding for the sodium channel and placed them in expression vectors to have the synthetic proteins placed in the membranes of the cultured cells. As a result, the cells no longer contract with the same force as the wild type.  why does this occur?

SIDE A SIDE B 5 g Glucose 0g Sucrose 100 mL Water jinarnitoij - 0.20M 0g Glucose 5 g Sucrose 100 mL Water Linannitol) 0.20 M Side A Side B How would you describe the level of water (the membrane is permeable to glucose but not permeable to sucrose) in this experiment after 5 days? Multiple Choice water level will be higher on side B water level will stay the same on both sides water level will be higher on side A water level will decrease on both sides

Question 4. Which of the following statements are true of kinases? A. They always bind to a dimeric ligand. B. They phosphorylate themselves or another protein. C. They must be associated with a G-protein to function. D. They always contain seven membrane-spanning domains. E. They always dephos phorylate proteins.

Which of the following drugs would you expect would prevent transformation of cells by the Rous Sarcoma Virus (RSV) (select all that appy)? A. Tyrosine Kinase Inhibitor B. Integrase Inhibitor C. Inhibitor GTPase Activity ✓ D. Reverse Transcriptase Inhibitor E. Staurosporine (inhibitor of Ser/Thr kinases)

Compound Sodium Lactate is isotonic solution. this mean that it  a. reduces movement of sodium across the membrane  b.prevent movement of water across the semi permerable cell membrane  c. promotes movement of water out of the cell d. facilitates equal movement of water across the semi permerable cell membrane

b) If you soak an animal cell that is permeable to both water and glucose in either 5.5% glucose or 0.9% NaCl (both isosmotic solutions), the cell exposed to 5.5% glucose will gain water, while the cell exposed to 0.9% NaCl will not gain water. Predict why this is the case.
