Outside the cell (extracellular fluid) Inside the cell (cytoplasm) Substances X

Question

Outside the cell (extracellular fluid) Inside the cell (cytoplasm) Substances X and Y may be any substances other than water. Letter size indicates relative concentrations of substances X and Y on each side of the membrane. Therefore, the concentrations of X and Y are greater inside the cell than outside. The solute concentrations of the extracellular fluid and cytoplasm are measured in milliosmols (mOsm). The membrane is permeable to water. Solute concentration: 500 mOsm Solute concentration 300 mOsm Plasma membrane (lipid bilayer) 47

Explanation / Answer

ANSWER-

2.) Passive transport occurs in the direction of higher to lower concentration,while active transport occurs in the direction of lower to higher concentration.

x<----------X PASSIVE TRANSPORT

y----------->Y ACTIVE TRANSPORT

3.)the flow of water towards outside the cell due to high concentration of solute outside the cell.
