IB Biology: A2.2-Eukaryotic Cell Structure

Multiple Choice

Explain how compartmentalization in eukaryotic cells benefits cellular processes.

• It prevents enzymes and substrates from interacting, slowing down metabolic reactions.

• It allows different cellular processes to occur simultaneously in specialized organelles, increasing efficiency and regulation.

• It forces all reactions to occur in one area of the cytoplasm, improving coordination.

• It reduces the complexity of the cell, making it similar to a prokaryote.

Multiple Choice

Why is the presence of a nucleus significant in eukaryotic cells?

• It helps the cell move.

• It produces energy directly.

• It stores waste products.
