First, drag labels to targets (a) and (b) to indicate whether these environments are hydrophilic or hydrophobic. 2.next, drag th
e phospholipid layers to targets (c) and (d) to indicate how they are oriented in the plasma membrane. 3.finally, drag labels to targets (e), (f), and (g) to indicate which portions of the membrane protein are hydrophilic and which are hydrophobic
First, both the extracellular fluid and the cytoplasm are hydrophilic. The phosphate head of the phospholipid is hydrophilic hence it either faces the extracellular fluid and the cytoplasm. The lipid tail of the phospholipid is hydrophobic hence it is confined in the middle of the plasma membrane. Both cytoplasmic and the extracellular fluid ends of the transmembrane protein are hydrophilic and the middle part of the transmembrane protein is hydrophobic.
