Question

Which of the following describes why phospholipids are better suited to forming the cell membrane than regular fats or steroids?

A. Their glycerol head allows them to bond easily with most other molecules.
B. Their phosphate group gives them a hydrophilic end.
C. Their three-pronged structure allows them to store large amounts of energy.
D. Their unique ringed structure provides them with the ability to regulate cell metabolism.

idk this one.. maybe B??

Answer 1

Yes it is B!

Phosphate group gives them a hydrophilic end! This allows for the molecules to form a semi permeable membrane

Answer 2

The correct answer would be B. Their phosphate group gives them a hydrophilic end.

The phosphate group in phospholipid is responsible for the amphiphilic nature of the phospholipid bilayer.

The phosphate group forms the hydrophilic end whereas the lipid chain forms the hydrophobic end.

The hydrophilic end enables the plasma membrane to interact with the substances inside and outside the cell.

It also provides the cell membrane its semi-permeable nature.

It provides stability to the membrane proteins present in the plasma membrane.
