Question

which statement best relates to how the structure of a lipid influences the lipids function? a phospholipid has a negatively charged head and a positively charged tail. the polar structure of the lipid makes it water repellent. a phospholipids uncharged head is attracted to the charged tail. the uncharged tail of a phospholipid is hydrophobic.

Explanation:

Phospholipids have a hydrophilic (charged) head and a hydrophobic (uncharged) tail. The hydrophobic nature of the tail makes it repel water. A is incorrect as the head is polar/charged and the tail is non - polar/uncharged, not oppositely charged as stated. B is incorrect because lipids are non - polar and non - polar substances are water repellent, not polar ones. C is incorrect as the head is charged and the tail is uncharged and they are not attracted to each other in that way. The uncharged tail being hydrophobic is a key structural feature influencing lipid function in cell membranes etc.

Answer:

The uncharged tail of a phospholipid is hydrophobic.
