OA, nonhydrolyzeable; GTP; insoluble; readily B. nonhydrolyzeable; ATP; insoluble; readily c. nonhydrolyzeable; ATP; soluble; readily D. nonhydrolyzeable; GTP; soluble; not E. nonhydrolyzeable; GTP; soluble; readily
DO NOT COPY THE ANSWER FROM THE SAME QUESTION. Sassa, a biology professor, wanted to demonstrate to her students the applicability of a dialyzing membrane (DM) as a model for the cell membrane by enclosing an aqueous solution in a DM bag and immersing in a beaker containing a different solution. Substances available which are permeable to the DM include 0.02 M NaCl, 0.03 M glucose, and 0.01 M glucose. The only substance available which is completely impermeable to the DM is the 0.01 M lactose. Using the substances given and materials such as a beaker, stirring rod, and string, draw ONLY ONE set-up that can be demonstrated by Ms. Sassa that will satisfy ALL of the following conditions:a. No solute will exhibit a net diffusion out of the cell.b. Glucose will exhibit a net diffusion into the cell.c. NaCl will exhibit a zero net d. No net movement of lactose from the inside to outside of the cell. Make sure to label properly the substance inside the beaker and inside the DM bag.
Select the single best answer. Which is the outstanding structural feature of an adipocyte? It has a polar and nonpolar region. The cells have a few small fat droplets. The fat droplets are surrounded by mitochondria. O A large fat globule takes up nearly the entire cytoplasm.

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
Protein: glucose transporter, Role: Sugar transport across the plasma membrane. Where is this protein synthesized? Be as specific as possible and briefly explain your choice
The "cell" has a sucrose concentration of 0.02M and a glucose concentration of 0.02M. The "environment" has a sucrose concentration of 0.06M and a glucose concentration of 0.02M. The membrane is permeable to both sucrose and glucose. This time the "cell" also contains an enzyme that will eventually breakdown and remove the sucrose that was initially in the cell and all other sucrose that may enter. 3.4 How does this differ from when there is no enzyme present? 711 SO Which way? MWLt S ns ve S anarios 1-32
After previewing the attached figure, choose the correct answer(s) bellow: * Glucose. Extracellular space Glucose transporter (state 1) Cell membrane Cytosol Glucose Extracellular space transporter (state 2) Cytosol Hexokinases irreversibly catalyze the phosphorylation of intracellular glucose to glucose 6-P, thereby trapping it Inside the cell because no cell membrane transporter exists for phosphorylated sugars. The GLUT abundant in muscle and adipose tissue is the Insulin-dependent GLUT-4 . Glucokinase has a high Km (it functions only when glucose concentration is high), a high Vmax (it functions efficiently when glucose concentration is high), and is not directly inhibited by glucose 6-P. Glucose transport hy GLITS is down a
Eukaryotic membrane fluidity can be decreased by which of the following mechanisms? decreasing the number of fatty acids attached to glycerol in membrane lipids increasing the number of carbons in the fatty acids of membrane lipids increasing the degree of unsaturation in the fatty acids of membrane lipids decreasing the number of membraned organelles in the eukaryotic cell increasing the number of branched-chain fatty acids of membrane lipids
