Frage 1
Frage
The main component of a biological membrane is a [blank_start]phospholipid[blank_end] [blank_start]bilayer[blank_end]. [blank_start]Hydrophilic[blank_end] heads face out while [blank_start]hydrophobic[blank_end] tails face in. The model is called a "[blank_start]fluid[blank_end] [blank_start]mosaic[blank_end] [blank_start]model[blank_end]" because there are several components making up the membrane, which all move laterally relative to each other.
