Proteins made from ribosomes attached to the rough
endoplasmic reticulum enter the lumen of the ER and move
to the smooth endoplasmic reticulum. A small vacuole
(vesicle) pinches off the smooth ER and carries the protein
to the Golgi apparatus, where it is further processed.

Mitochondria are bounded by a double membrane. The inner
membrane is folded to form little shelves, called cristae,
which project into the matrix, an inner space filled with

hormones. In the liver, smooth ER is involved in the
detoxification of drugs, including alcohol.

The Golgi apparatus is composed of a stack of about a
half dozen or more saccules (flattened vacuoles, which
look like hollow pancakes). One side of the stack, called
the inner face, is directed toward the nucleus and the
ER. The other side of the stack, called the outer face,
is directed toward the cell membrane.
