Final answer:
Glucose would move into the cells from an outside concentration of 10 mM to an inside concentration of 1 mM by the process of diffusion. No net flow of glucose would occur if concentrations were equal inside and outside unless other cellular mechanisms influenced movement.
Step-by-step explanation:
The question pertains to the movement of glucose across a cell membrane when there are different concentrations of glucose inside and outside the cell. This movement is governed by the principle of diffusion, which is the net movement of particles from an area of higher concentration to an area of lower concentration. In the scenario provided, with a concentration of 10 mM glucose on the outside and 1 mM glucose on the inside, glucose would move into the cells if the membrane is permeable to glucose. This is because there is a higher concentration of glucose outside the cell, and diffusion drives glucose to move down its concentration gradient into the cell where it is less concentrated.
If the concentration of glucose were equal inside and outside of the cell, there would likely be no net flow of glucose across the cell membrane because the forces driving diffusion would be balanced. However, biological membranes are complex, and sometimes other factors such as transporter proteins or cellular energy (ATP) can influence movement even when concentrations are equal.
