Freeze-fracturing is a useful tool for revealing _______ proteins.
A) peripheral
B) cytosolic
C) asymmetric
D) cytoskeletal
E) transmembrane

Question

Quizplus · Accepted Answer

Freeze-fracturing is a technique used to study the internal structure of cell membranes. Since it involves rapidly freezing and fracturing the membrane, it is particularly useful for studying transmembrane proteins - those that span the lipid bilayer of the membrane. Therefore, the best choice is E) transmembrane proteins. Peripheral, cytosolic, asymmetric, and cytoskeletal proteins are not specifically studied using freeze-fracturing.
