2.9 Cell Compartmentalization

Describe the membrane-bound structures of the eukaryotic cell.

• Membranes and membrane-bound organelles in eukaryotic cells compartmentalize intracellular metabolic processes and specific enzymatic reactions.

Explain how internal membranes and membrane-bound organelles contribute to compartmentalization of eukaryotic cell functions.

• Internal membranes facilitate cellular processes by minimizing competing interactions and by increasing the surface area where reactions can occur.
