Unit 2 - AP Biology Exam Review

Front

What is the primary reason small cells are more efficient at obtaining nutrients?

Back

Small cells have a larger surface area-to-volume ratio, allowing for more efficient nutrient absorption.

Front

How can you identify eukaryotic cells based on their structures?

Back

Eukaryotic cells have membrane-bound organelles.

Front

What is the significance of ATP in cellular processes?

Back

ATP provides the energy required for various cellular processes, including active transport.

Front

What is the difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells lack membrane-bound organelles and a nucleus, while eukaryotic cells have both.

Front

What is facilitated diffusion?

Back

The process of passive transport of molecules across a cell membrane via specific transmembrane integral proteins.

Front

Define prokaryotic cells.

Back

Cells that lack a nucleus and membrane-bound organelles.

Front

Define eukaryotic cells.

Back

Cells that have a nucleus and membrane-bound organelles.

Front

What role does the cell membrane play in cellular function?

Back

The cell membrane regulates what enters and exits the cell, maintaining homeostasis.

Front

What is the function of ribosomes in a cell?

Back

Ribosomes are responsible for protein synthesis.

Front

What is the role of mitochondria in cells?

Back

Mitochondria are the powerhouses of the cell, generating ATP through cellular respiration.
