The Membrane of a Gas Vesicle is Composed Of

Question

The membrane of a gas vesicle is composed of
A) various phospholipids.
B) proteins.
C) carbohydrates.
D) both glycoproteins and phospholipids.

Accepted Answer

Gas vesicles are composed of a protein shell, usually consisting of a single protein called GvpA that self-assembles into a cage-like structure. The protein shell is impermeable to water and acts as a permeability barrier, allowing gases to be selectively accumulated inside the vesicle. Therefore, the membrane of a gas vesicle is composed of proteins rather than phospholipids or carbohydrates.
