Question

Which of the following correctly describe(s) the normal structures and functions of the plasma membrane, described by the fluid mosaic model?

  

A.The type of transmembrane protein complexes that a cell has in its membrane determine which materials can be shuttled in and out of the cell if they are polar or large.

B.glycoproteins contribute to the identification of cells

  C.the selective permeability of the plasma membrane is a function of the phospholipid bilayer

D.amino acids embedded in the bilayer serve as receptors

Answer 1

Which of the following correctly describe(s) the normal structures and functions of the plasma membrane, described by the fluid mosaic model?

  

A.The type of transmembrane protein complexes that a cell has in its membrane determine which materials can be shuttled in and out of the cell if they are polar or large.- This is correct as transmembrane proteins allow polar molecules pass through it.

B.glycoproteins contribute to the identification of cells- They help to identify the type of cell.

  C.the selective permeability of the plasma membrane is a function of the phospholipid bilayer- Plasma membrane is mainly made up of lipids. These lipids do not allow polar molecules to enter inside it.

D.amino acids embedded in the bilayer serve as receptors- Amino acids are not receptors but proteins are the receptors.

So, it is incorrect.

Correct answers are a,b and c.
