outer membrane
Exterior bounding skin
The outer membrane is the external layer of a double-membrane structure, especially in biology.
Gram-negative bacteria have an outer membrane surrounding their cell wall.
Mitochondria and chloroplasts each have an outer membrane enclosing an inner one.
The outer membrane typically controls what enters and exits: The antibiotic disrupts the bacterial outer membrane.
