Osmosis Practice Activity Osmosis is the diffusion of water from an area of high concentration to an area of low concentration. Only water moves in osmosis! The diagrams below show the concentration of water and salt inside the cell and the concentration of water and salt surrounding the cell. Complete the sentences below by comparing the concentration of the water inside the cell and the concentration outside the cell. 1. a. Water will flow the cell, out of the cell, in both directions). (into 5% NaCl 95% H20 95% NaCI 5% H20 b. The cell will (shrink, burst, stay the same). a. Water will flow (into the cell. 2. 5% NaCl out of the cell, in both directions). 5% NaCl 95% H20 95% H20 b.

Link each process with the correct deﬁnition. RECEPTORMEDIATED ENDOCYTOSIS PHAGOCYTOSIS PINOCYTOSIS EXOCYTOSIS 1. A cell ingests a large particle, such as a bacterial cell. 2. Receptor proteins embedded in the membrane recognize specific surface characteristics of substances. 3. A transport vesicle inside the cell approaches the plasma membrane of the cell, fuses with it, and releases its contents to the outside of the cell. 4. A vesicle containing whatever molecules are in solution outside the cell bulges inward, pinches off, and enters the cell.

What appears to be the effect of inserting a protein channel into the membrane on the movement of molecules across the membrane? 11. Is the inner surface (facing the channel) of the embedded protein likely to be polar or nonpolar in the examples shown in Model 4? Is the exterior surface (facing the fatty acid chains of the phospholipids) of the embedded protein likely to be polar or nonpolar? Explain your reasoning. When a membrane protein assists in the passive transport of molecules across a barrier in the direction down their concentration gradient (from high concentration to low concentration) it is called facilitated diffusion. Transport proteins may also be involved in active transport where the cell uses energy from…
