The Na –glucose symport system of intestinal epithelial cells couples the \"downhill\" transport of two Na ions into the cell to the \"uphill\" transport of glucose, pumping glucose into the cell against its concentration gradient. If the Na concentration outside the cell ([Na ]out) is 155 mM and that inside the cell ([Na ]in) is 17.0 mM, and the cell potential is -53.0 mV (inside negative), calculate the maximum ratio of [glucose]in to [glucose]out that could theoretically be produced if...
The Na –glucose symport system of intestinal epithelial cells couples the "downhill" transport of two Na ions into the cell to the "uphill" transport of glucose, pumping glucose into the cell against its concentration gradient. If the Na concentration outside the cell ([Na+]out) is 163 mM and that inside the cell ([Na+]in) is 17.0 mM, and the cell potential is -53.0 mV (inside negative), calculate the maximum ratio of [glucose]in to [glucose]out that could theoretically be produced if the energy...
5/2400 Resources Give Up Hint Intestinal epithelial cells pump glucose into the cell against its concentration gradient using the Nat-glucose symporter. Recall that the Nat concentration is significantly higher outside the cell than inside the cell. The symporter couples the "downhill" transport of two Nations into the cell to the "uphill" transport of glucose into the cell. If the Na+ concentration outside the cell (INa1.) is 151 mM and that inside the cell ([Na]) is 23.0 mm, and the cell...
What more info do you need? This is all I've been provided. 1. 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. (opts) a. If the Na concentration outside the cell ([Na Jou) is 161 mM...
HW 11-1 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 149 mM and that inside the cell ( [ Na + ] in ) is 19.0 mM, and the cell potential is −...
The Na glucose symporter transports glucose from the lumen of the small intestine into cells lining the lumen. Transport of 1 glucose molecule is directly coupled to the transport of 2 Nations into the cell. 2 Na*(out) + 1 glucose(out) - 2 Nat(in) + 1 glucose(in) Assume the following conditions at 37 °C: [Nalin - 12 mm, [Na lout = 145 mm, (glucoseJout = 28 pm, and Ay =-72 mV (inside negative). Faraday constant F = 96,485 C/mol, ideal gas...
1. Animal cells have a Na,K pump that couples the energy of ATP hydrolysis to transport 3 Na ions out of the cell and 2 K ions into the cell. Inside astrocytes, the concentration of Na is 20 mM and the concentration of K is 130 mM. The extracellular concentrations of Na and K are 145 mM and 5 mM, respectively. Calculate the energy required for the transport of Na and K , with this stoichiometry; assume that the cell...
1) Glucose enters human enterocytes (intestinal epithelial cells) against its concentration gradient. A Na+ ion enters the cell with each glucose molecule, and while the glucose transporter does not hydrolyze ATP, it depends on a pre-existing gradient of Na+ ions that is created by the Na+/K+ ATPase. This is an example of ____________. A. primary active uniport B. secondary active antiport C. primary active symport D. secondary active symport 2) Which statement is FALSE? A. Acetyl CoA is oxidized to...
