Unit 2 · 2.9 — Cell Compartmentalization [cite: 9, 28]

Everything to learn here

• Concept: Internal membrane partitioning in eukaryotic cells establishes isolated microenvironments, allowing simultaneous, incompatible metabolic processes to occur efficiently [cite: 10, 30].
• Concept: Prokaryotes lack internal membrane-bound organelles but possess localized, specialized internal regions (e.g., the nucleoid region for DNA) [cite: 14, 33].
• Skill: FRQ Task Verb "Support a Claim" — Support a claim regarding the evolutionary advantages and energetic costs associated with heavy cellular compartmentalization [cite: 19, 22, 30].
• Concept: Explain how internal membranes increase efficiency by separating competing chemical reactions and increasing surface area.
• Concept: Describe how membrane-bound compartments minimize interference between metabolic processes to optimize cellular function.
