The concentration of glucose in the digestive tube cell is higher than that of the digestive tube lumen. Glucose enters the cell from the digestive tube lumen through transport protein Y; this movement is driven by the movement of sodium through transport protein Y. Glucose is therfore moving into the cell by: O faciltated diffusion O secondary active transport; energy is used directly to move sodium from the digestive tube lumen into the cell O secondary active transport; energy is used directly to move sodium from the digestive tube cell into the blood O primary active transport; energy is used directly to move the glucose from the digestive tube lumen into the cell

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.
