Which membrane protein type would likely be removed most easily from a cell membrane in a laboratory experiment?
A) Integral proteins
B) Channel proteins
C) Peripheral proteins
D) Transmembrane proteins
E) Gated channels

Question

Quizplus · Accepted Answer

Peripheral proteins are loosely bound to the membrane and can be easily removed by mild disruption of the membrane, such as with a change in pH or through the use of detergents. In contrast, integral proteins, transmembrane proteins, and channel proteins are embedded within the membrane and require more drastic measures to remove, such as the use of harsh detergents or extreme pH or temperature conditions. Gated channels are a subtype of channel proteins and would also require more drastic measures to remove. Therefore, peripheral proteins would likely be the easiest membrane protein type to remove in a laboratory experiment.
