According to the Fluid Mosaic Model of Membrane Structure, Proteins

Question

According to the fluid mosaic model of membrane structure, proteins of the membrane are mostly
A) spread in a continuous layer over the inner and outer surfaces of the membrane.
B) confined to the hydrophobic interior of the membrane.
C) embedded in a lipid bilayer.
D) randomly oriented in the membrane, with no fixed inside-outside polarity.
E) free to depart from the fluid membrane and dissolve in the surrounding solution.

Accepted Answer

According to the fluid mosaic model of membrane structure, proteins are embedded in a lipid bilayer. This means that they are not spread in a continuous layer over the inner and outer surfaces of the membrane (A), not confined to the hydrophobic interior of the membrane (B), not randomly oriented in the membrane with no fixed inside-outside polarity (D) and not free to depart from the fluid membrane and dissolve in the surrounding solution (E).
