Question

multiple choice question
which is the model that describes the phospholipids in the bilayer as a \sea\ in which other molecules can float?

○ protein transport model

○ phospholipid bilayer model

○ selective permeability model

○ fluid mosaic model

Explanation:

The Fluid Mosaic Model describes the cell membrane's structure, where phospholipids in the bilayer are a "sea" (fluid) with proteins and other molecules floating in it. The Protein Transport Model focuses on protein - mediated transport, the Phospholipid Bilayer Model just describes the bilayer structure without the "floating" concept, and the Selective Permeability Model is about the membrane's permeability, not the structure's description as a fluid sea.

Answer:

D. Fluid mosaic model
