These flashcards cover the key concepts related to the cell compartmentalization topic discussed in AP Biology.

What is the primary function of internal membranes and membrane-bound organelles in eukaryotic cells?

They compartmentalize the cell and help facilitate intracellular reactions.

How do membranes minimize competing interactions in cellular processes?

By allowing different reactions to occur in separate compartments, reducing interference between those reactions.

What is the role of lysosomes in a eukaryotic cell?

Lysosomes contain hydrolytic enzymes for chemical digestion that function best in an acidic environment.

What happens if lysosomal membranes are damaged?

Hydrolytic enzymes can leak into the cytoplasm, leading to chemical digestion that can cause severe cell damage or death.

How does membrane folding in organelles like mitochondria increase cellular efficiency?

Folding increases surface area for metabolic reactions, such as ATP synthesis during electron transport.

What is the significance of thylakoids in chloroplasts?

Thylakoids are highly folded membrane compartments that enhance the efficiency of light-dependent reactions in photosynthesis.

What effect does damage to internal membranes have on cellular functions?

It can hinder proper cell function by disrupting compartmentalization and enzymatic processes.

What prediction can be made regarding the rupture of lysosomal membranes due to viral infections?

Hydrolytic enzymes will be released, leading to potential cell death.

Why is compartmentalization important for eukaryotic cells?

It increases efficiency in carrying out functions by allowing different reactions to occur simultaneously without interference.

What are the key takeaways about eukaryotic cells and compartmentalization?

Eukaryotic cells have membrane-bound organelles that compartmentalize processes, enhancing efficiency and minimizing competition.
