Question

Which of these parts of the membrane help large molecules pass through it?

A. Phospholipid bilayers
B. Phosphorus groups
C. Globular proteins
D. Fatty acids

Answer 1

Globular proteins! The other answer is sadly wrong.

Step-by-step explanation:

I just took the quiz. Many globular proteins positioned throughout the cell membrane help the large, polar molecules across. These globular proteins in the cell membrane are the membrane proteins.

Also, I accidently put a 1 star on my own answer, but it's correct.

Answer 2

A. Phospholipid bilayer

Step-by-step explanation:

Cell membrane is a selective permeable structure in all living cells that allows the passage of some molecules and disallows some. This function of the cell membrane is attributed to the PHOSPHOLIPID BILAYER CONTENT of its structure.

The phospholipid bilayer contains both a hydrophobic end (water fearing) and hydrophilic end (water loving). The interaction of the molecules with these regions of the membrane serves as the basis for the movement of molecules across the cell membrane.
