|
Contents of a cell that are contained wtihin its plasma membrane but, in the case of eukaryotic cells, outside the nucleus.
|
Cytoplasm
|
|
Protein sorting signal that consists of a specific three-dimensional arrangement of atoms on the folded protein's surface.

Gated transport
|
|
Membrane-enclosed compartment in a eukaryotic cell that has a distinct structure, macromolecular composition, and function.

|
Protein sorting signal that consists of a short continuous sequence of amino acids.

|
Why are biological membranes selectively permeable?
|
Because of the proteins located in the membrane.
|
|
Are membrane-bound and free ribosomes structurally and functionally identical?
|
Yes, they differ only in the proteins they happen to be making at a particular time.
|
|
What do signal sequences specify?
|
A particular destination in the cell.
|
|
What is the fate of a protein with no sorting signal?
|
It will remain in the cytosol.
