Question

resthe system below, two compartments are o n each compartment are showr. n action potential occurring (I pt.) separated by a typical lipid bilayer. The concentrations of glucose a typu XY 0 o O o gradient (1 pt.)? hent contains the highest solute concentration? In which direction is the solute concentration 12. Which compartment contains the highest water concentration? In which direction is the water concentration gradient (1 pt.)? In the system depicted above, the lipid bilayer is not permeable to the solute (glucose) 13. Which substance will move in the system, and in what direction (1 pt.)? hich of the figures below represents the volumes of X and Y at equilibrium (1 pt.)? XY XY B. C. D. E. A. 15. Lipid synthesis occurs in which of the following locations of a cell (1 pt.)? A. Trans-Golgi network B. Granular, or "rough," endoplasmic reticulum C Agranular, or "smooth," endoplasmic reticulum . Nucleus E. Lysosome 16. List the direction and magnitude of K" and Na movement by the Na -K pump (1 pt.).

Explanation / Answer

11. Compartment Y contains the highest solute (glucose) molecules. Solute concentration is more in Y compartment.

12. Compartment X contains high water concentration. Watee concentration gradient is from X to Y.

13. In this system water will move from X direction to Y direction, like a type of passive transfer.

14. At equilibrium, enough water molecules would move from X compartment to Y compartment and thus ' B option' will be the correct option.

C is not OK because some level of X also move down from the already existing mark

E is not OK because some level of Y also rises up from already existing level mark
