Enveloped viruses have a lipid-based membrane surrounding the protein capsid. This envelope is partly composed of the cell membrane within which the virus replicated, and it contains proteins and carbohydrates. Some of the proteins are from the host cell and some are from the virus..
A membrane can be lipid bilayer that surrounds a cell- a cell membrane â or it can be a thin layer of tissue made up of many different cells. The cell membrane controls what enters and leaves the You do not have access to view this node, but at the tissue layer, a membrane forms a barrier. A serous membrane belongs to this second type of membrane. Serous membrane is also known as âserous tunicâ.
