Question

refer to the figure. which of the following is true regarding the labeled plasma membrane? multiple choice parts x and y are hydrophilic. parts w and y are hydrophobic. parts w and z are hydrophilic. parts w and x are hydrophilic.

Explanation:

The plasma - membrane is a phospholipid bilayer. The heads (W and Z) are hydrophilic and the tails (X and Y) are hydrophobic. So, the statement that parts W and Y are hydrophobic is incorrect as W is hydrophilic. The correct statement is that parts W and Z are hydrophilic since they are the polar, water - loving heads of the phospholipids.

Answer:

Parts W and Z are hydrophilic.
