Separating the Cell Membrane

CELLS-BS4GHY

During lab, a student is asked to rapidly freeze then fracture a cell membrane. The student finds that the cell membrane breaks along the middle of the phospholipid bilayer.

The student is able to conclude that

A

the cell membrane is weakest along the middle due to the properties of the hydrophobic lipid region.

B

the cell membrane's phosphate content freezes quickly and causes the fracturing to occur.

C

the integral proteins spanning the cell membrane are too weak to hold the cell membrane together.

D

rapid freezing practices in the laboratory setting will cause most molecules to dissociate their bonds and break.
