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.

In the fluid mosaic model: plasma membrane proteins orient their hydrophilic sides toward the internal bilayer. phospholipids often flip-flop between the inner and outer layers. the mosaic refers to proteins attached to the underlying cytoskeleton. the fluid refers to the phospholipid bilayer. the mosaic refers to the symmetry of the internal membrane proteins and sterols.

Which of the following statements are correct? P. Plasma membrane is highly impermeable to all charged molecules Q. All membrane transport proteins so far known, are transmembrane multipass proteins R. Ionophores operate by shielding the charge of the transported ion so that it can penetrate the hydrophobic interior of the lipid bilayer. S. Na+-K+ ATPase exchanges equal numbers of Na+ and K+ ions in each pumping cycle P and Q R and S P and S Q and R
In facilitated diffusion and active transport, how do transport proteins affect the rate of movement of molecules across the phospholipid selectively permeable membrane? A Transport proteins decrease the rate of movement of molecules. B Transport proteins stop the rate of movement of molecules. © Transport proteins increase the rate of movement of molecules. Transport proteins ensures all molecules may pass the membrane simultaneously.
The average concentration of salt in seawater is about 3.5 percent and the average concen- tration of salt in the human cellular environment is about 0.9 percent. Drinking seawater can be fatally harmful and is highly discouraged even in the most severe cases of dehydration. Which of the following provides the most likely cause for this fact? A B с D The increase in salt concentration in the extracellular environment will increase the per- meability of the cell membrane. The increase in salt concentration in the extracellular environment will cause the move- ment of water into the cell. The increase in salt concentration in the extracellular environment will cause the move- ment of water out of the cell. The increase in salt concentration in the extracellular environment will decrease the per- meability of the cell membrane.
Various types of vesicle coats have been implicated in membrane traffic pathways suchas endocytosis, export from the ER to the Golgi, and transport between Golgicisternae. But so far, no coat has been identified for the secretory vesicles that carrymaterial from the Golgi to the plasma membrane. Do you think such a coat is likely toexist? Justify your answer.
Which of the following is an incorrect description of components of the biological membrane? a. Hydrocarbon tail without carbon-carbon double bonds is saturated with respect to hydrogen. b. The movement of proteins in a bilayer can be monitored using FRAP С. Most of the lipids and some of the proteins cannot move sideways in the plane of the membrane and mostly a lipid may 'flip-flop' across the membrane from one phospholipid layer to the other O d. Cholesterol is a steroid which is wedged between phospholipid molecules of the plasma membranes of animal cells e. A kink in one of the hydrocarbon tails results from the presence of carbon-carbon double bonds and causes increased fluidity of the membrane
