- The following table shows experimental results of the glucose transport rate, mM/sec, following facilitated diffusion by glucose carrier proteins. (Recall: the starting conc. L represents glucose added to one side of the membrane; distilled water, omM of glucose was added to the other side of the membrane). The rate of glucose transport was 0.0031 mm/sec with 8mM of glucose (run number 4, highlighted); the rate decreased to 0.0017 mM/sec with 10mM of glucose (run 5, highlighted). Why was the rate of glucose transport slower when the concentration gradient was increased?

Explain which one or ones of these classes is able to move glucose and which can move bicarbonate (HCO3−) against an electrochemical gradient. In the case of bicarbonate, but not glucose, the ΔG of the transport process has two terms. What are these two terms, and why does the second not apply to glucose? Why are cotransporters often referred to as examples of secondary active transport?The average time it takes for a molecule to diffuse adistance of x cm is given byt = x2/2D where t is the time in seconds and D is the diffusioncoefficient. Given that the diffusion coefficient ofglucose is 5.7 × 10−7cm2/s, calculate the time it wouldtake for a glucose molecule to diffuse 10 μm, which isroughly the size of a cell.
- Intestinal epithelial cells pump glucose into the cell against its concentration gradient using the Na+– glucose symporter. Recall that the Na+ concentration is significantly higher outside the cell than inside the cell. The symporter couples the "downhill" transport of two Na+ ions into the cell to the "uphill" transport of glucose into the cell. If the Na+ concentration outside the cell ([Na+]out) is 163 mM and that inside the cell ([Na+]in) is 21.0 mM, and the cell potential is −54.0 mV (inside negative), calculate the maximum energy available for pumping a mole of glucose into the cell. Assume the temperature is 37 °C.Intestinal epithelial cells pump glucose into the cell against its concentration gradient using the Na*-glucose symporter. Recall that the Na+ concentration is significantly higher outside the cell than inside the cell. The symporter couples the "downhill" transport of two Na+ ions into the cell to the "uphill" transport of glucose into the cell. If the Na+ concentration outside the cell ([Na* lout) is 147 mM and that inside the cell ([Na+]in) is 17.0 mM, and the cell potential is -54.0 mV (inside negative), calculate the maximum energy available for pumping a mole of glucose into the cell. Assume the temperature is 37 °C.

If the Na+ concentration outside the cell ([Na+]out) is 155 mM and that inside the cell ([Na+ lin) is 21.0 mM, and the cell potential is -52.0 mV (inside negative), calculate the maximum energy available for pumping a mole of glucose into the cell.

- Estimate the flux (mg/cm2/s) by diffusion of estrogen (a steroid) through a lipid bilayer cell membrane when assuming the diffusion coefficient for estrogen across the lipid bilayer is 10^–6 cm2/s, and that the initial concentration of estrogen in the extracellular fluid is 1 ng/mL and 0 in the cytoplasm.(b) The GLUT system is highly selective for glucose. It also speeds up the rate of glucose transport across the membrane by as much as 100-fold when compared to the passive diffusion of glucose across a bilayer in the absence of any transport system. While impressive, this rate of transport is much slower than purely diffusion limited rate of movement (ie. the fastest a molecule can move by diffusion). Given this fact, on the blank plot below draw the expected relationship between the rate of GLUT-mediated transport and increasing [glucose]? Use the space below the graph to explain your answer. fast Transport Rate slow low [glucose] high (c) Next, use a dashed line on the same plot above to draw the shape of the curve when the amount of GLUT transporters in the membrane is cut in half. Briefly explain your answer in the space provided below the graph.Table K₁ (T1) Vmax (T1) Kt (T2) Vmax (T2) 1 1.12 mM 125 nmole/min None of the above. 3.0 mM 130 nmole/min Based on these values, what are your conclusions? O T1 is most likely a cell that expresses a high affinity transporter for glucose. T2 is most likely a cell that expresses a high affinity transporter for glucose. T1 must be a cell expressing the insulin-dependent glucose transporter. Each transporter has a similar Vmax and therefore both T1 and T2 are the same cell type.
- If a skeletal muscle has depleted its stores of ATP how will the altered transport properties of the following transporters affect cytosolic ion concentrations (increase, decrease, no change) relative to normal? Skeletal Muscle Cell With Depleted ATP Stores Ion transporter Cytosolic K+ Cytosolic Na+ Cytosolic Ca2+ NKA NCX SERCABelow find the structures for ibogaine and cocaine. Ibogaine and cocaine inhibit the dopamine active transporter (DAT). This transporter is a secondary active transporter, and depends on the primary active transporter Na+/K+ ATPase. Ibogaine had a Kι = 2 μM, and cocaine a Kι = 0.64 μM respectively. (a) Define secondary active transport. (b) Is ibogaine an effective treatment for cocaine based on DAT binding?Intestinal epithelial cells pump glucose into the cell against its concentration gradient using the Na-glucose symporter. Recall that the Na* concentration is significantly higher outside the cell than inside the cell. The symporter couples the "downhill" transport of two Na* ions into the cell to the "uphill" transport of glucose into the cell. If the Nat concentration outside the cell ([Na lout) is 141 mM and that inside the cell ([Na* lin) is 19.0 mM, and the cell potential is -52.0 mV (inside negative), calculate the maximum energy available for pumping a mole of glucose into the cell.
