Unit 2 AP Biology Insta-Review (Cell Structure & Function)

Front

What is the direction of water flow when the extracellular solution is 0.5M and the cell is 1.0M?

Back

Water will flow into the cell towards the hypertonic solution.

Front

What is the process of exporting materials from a cell using vesicles called?

Back

Exocytosis.

Front

Is the transport membrane protein specific?

Back

True.

Front

What is the pathway to exocytosis?

Back

Rough ER → Golgi → Membrane.

Front

How do carrier proteins demonstrate specificity for transport?

Back

The active site binds to the solute.

Front

Define hypertonic solution.

Back

A solution with a higher concentration of solutes compared to another solution.

Front

Define hypotonic solution.

Back

A solution with a lower concentration of solutes compared to another solution.

Front

What is osmosis?

Back

The movement of water across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is endocytosis?

Back

The process of taking materials into the cell by engulfing them in a vesicle.

Front

What role do lysosomes play in a cell?

Back

Lysosomes contain enzymes that break down waste materials and cellular debris.
