Topic 2.9: Cell Compartmentalization
Learning Objective: 2.9.A
Describe the membrane-bound structures of the eukaryotic cell.
Essential Knowledge: 2.9.A.1
Membranes and membrane-bound organelles in eukaryotic cells compartmentalize intracellular metabolic processes and specific enzymatic reactions.
Learning Objective: 2.9.B
Explain how internal membranes and membrane-bound organelles contribute to compartmentalization of eukaryotic cell functions.
Essential Knowledge: 2.9.B.1
Internal membranes facilitate cellular processes by minimizing competing interactions and by increasing the surface area where reactions can occur.
