Snake venom contains the enzyme phospholipase A2, which cleaves the fatty acid at position 2 of a phospholipid. Draw a phospholipid of your choice. Then draw the same phospholipid, but after it has been cleaved by phospholipase A2. How would this change affect the structure of a cell membrane?

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.

Cholesterol is abundant in the plasma membrane. Would you expect cholesterol to flipbetween the two leaflets of the membrane faster than phospholipids, or slower, or atthe same rate?
Phospholipids form the main fabric of the plasma membrane. One feature of phospholipids is that when they are placed in an aqueous solution, they will self-assemble into a double layer (bilayer) that resembles the bilayer of the plasma membrane. This self-assembly occurs because phospholipids are hydrophilic at one end (the phospholipid head) and hydrophobic at the other end (the phospholipid tails). Drag the labels to their appropriate locations in the figure. 1. First, drag labels of Group 1 to targets (a) and (b) to indicate whether these environments are hydrophilic or hydrophobic. 2. Next, drag the phospholipid layers (Group 2) to targets (c) and (d) to indicate how they are oriented in the plasma membrane. 3. Finally, drag labels of Group 1 to targets (e), (f), and (g) to indicate which portions of the membrane protein are hydrophilic and which are hydrophobic.
