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.

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.
