. Please describe the transportation of glucose after a meal when glucose is plentifuloutside cells? How is the transport protein that would transport glucose called? Whatwould be the direction of transportation? Would it be active or passive transport? Whatwould be driving force for the glucose transport: chemical gradient or electrochemicalgradient?
The rate at which the Na+K+ pump operates is not constant but is controlled by a combined effect of changes in ICF Na+ concentration and ECF K+ concentration. Do you think the changes in both ICF Na+ and ECF K+ concentration following a series of action potentials in a neuron would accelerate, slow down, or have no effect on the Na+K+ pumps in this cell?

Calculate the maximum ratio that can be achieved by the plasma membrane Na+-glucose symporter of an epithelial cell when [Na+]in is 12 mM, [Na+]out is 145 mM, the membrane potential is −50 mV (inside negative), and the temperature is 37 °C.
these are KT values. Which transporter that is a GLUT will transport glucose from blood which is 5nm at the maximum or Vmax? Is it (GLUT 11,KT= 0.1M), (is it GLUT1, KT = 3nm), (is it GLUT 2, KT= 17nm), (or GLUT 4, KT = 5nm)
Which of the following statements best describes the absorption of glucose? Absorption of glucose requires digestion by aminopeptidases on absorptive epithelial microvilli before absorption of the carbohydrate smaller units such as glucose. Absorption of glucose requires an electrochemical gradient of high extracellular K+ set up by primary active transport. Absorption of glucose occurs at villi and crypts mainly in the duodenum where amylases break down carbohydrates into glucose. Absorption of glucose occurs at the transporting epithelia in the small intestine and is a secondary active transport that requires a Na+gradient
