What is the name of the currently accepted model of membrane structure, and where does it place membrane proteins?
A) fluid- mosaic; on the surfaces of the membrane only
B) sandwich; on the outside and inside surfaces of the membrane only
C) sandwich; embedded within the membrane and on the surfaces of the membrane
D) fluid- mosaic; embedded within the membrane and on the surfaces of the membrane

Question

Quizplus · Accepted Answer

The currently accepted model of membrane structure is the fluid-mosaic model, which proposes that the membrane is a fluid phospholipid bilayer with embedded proteins that are free to move and interact with each other. Therefore, membrane proteins are both embedded within the membrane and on the surfaces of the membrane. Option A is incorrect because membrane proteins are not restricted to the surfaces of the membrane. Option B is incorrect because it suggests that membrane proteins are only present on the outside and inside surfaces of the membrane and not embedded within it. Option C is partially correct in acknowledging that membrane proteins are embedded within the membrane but is incorrect in suggesting that they are only on the surfaces of the membrane.
