Glucose transport across cell membranes varies depending upon blood glucose levels.  When glucose levels are high, glucose transport is accomplished via membrane transporters.  When glucose concentrations are low, the transport of glucose across the membrane is dependent upon the sodium ion concentration.  What types of transport is observed for glucose? A)simple diffusion at high [glucose], secondary active transport at low [glucose] B)facilitated diffusion at high [glucose], secondary active transport at low [glucose] C)simple diffusion at high [glucose], primary active transport at low [glucose] D)facilitated diffusion at high [glucose], primary active transport at low [glucose]

Osmosis

In simple words, osmosis is the slow, gradual movement of a liquid through a membrane. But there are nuances to this process. For instance, there has to be an imbalance in the distribution of solute in the liquid on either side of the membrane, which has to be semipermeable. The liquid in the region with a lower solute concentration moves to the region with a higher concentration, thereby displacing the solution in the process. The objective is to equalize the concentration of molecules on both sides of the membrane; the displacement of liquid can be viewed as a byproduct of this equalization. Since there is no energy required to carry osmosis, it is considered a passive process.
