Question

Which of the following aspects of membrane protein movement is explained by the fluid mosaic model? Group of answer choices

A) proteins that are immobile are often esterified to cholesterol via an Asp residue
B) proteins that are mobile only in a small area are sequestered by proteins attached to the cytoskeleton
C) proteins that freely diffuse through the membrane often undergo flip-flopping
D) proteins confined to a lipid raft are linked to phosphatidylserine via an amide bond

Answer 1

Option (B).

Step-by-step explanation:

The plasma membrane is made of the proteins and the lipid bilayer. Carbohydrates are attached in moiety with lipids and proteins. Plasma membrane is semi permeable in nature.

The mobile as well as immobile proteins are present in the plasma membrane. The small mobile proteins are remains in the proteins that are attached with the cytoskeleton. The proteins attach with the cytoskeleton shows shows small movement.

Thus, the correct answer is option (B).
