FINAL EXAM B.5 ATBAT

Front

What is actin?

Back

Actin is a structural protein that forms microfilaments, playing a crucial role in cell shape and movement.

Front

What is the shared function of carbohydrates and lipids in cells?

Back

Energy storage is a shared function of carbohydrates and lipids.

Front

What distinguishes prokaryotic cells from eukaryotic cells?

Back

Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells are more complex and have these structures.

Front

What is active transport?

Back

Active transport is the movement of substances across a cell membrane against their concentration gradient, requiring energy in the form of ATP.

Front

What is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy, occurring along the concentration gradient.

Front

What are eukaryotic cells?

Back

Eukaryotic cells are complex cells that contain a nucleus and membrane-bound organelles.

Front

What are prokaryotic cells?

Back

Prokaryotic cells are simpler cells that do not have a nucleus or membrane-bound organelles.

Front

What is the role of carbohydrates in cells?

Back

Carbohydrates serve as a primary energy source and play a role in structural support.

Front

What is the role of lipids in cells?

Back

Lipids are important for energy storage, insulation, and making up cell membranes.

Front

What is the difference between active and passive transport?

Back

Active transport requires energy (ATP) to move substances against their concentration gradient, while passive transport does not require energy and moves substances along the gradient.
