Cellular Transport Review

Front

What is Active Transport?

Back

The movement of materials against a concentration difference (from low to high), requiring energy.

Front

What is Passive Transport?

Back

The movement of materials across a cell membrane without the use of energy, typically from an area of high concentration to an area of low concentration.

Front

Define Diffusion.

Back

The process by which particles naturally vibrate and move from an area of high concentration to an area of lower concentration.

Front

What is a Hypertonic Solution?

Back

A solution that has a higher concentration of solutes compared to another solution, causing water to move out of cells.

Front

What is Pinocytosis?

Back

The process of moving large amounts of liquid into the cell using energy.

Front

What is Phagocytosis?

Back

The process of engulfing large particles or cells into the cell using energy.

Front

What is Exocytosis?

Back

The process of expelling materials from the cell using energy.

Front

What role does ATP play in Active Transport?

Back

ATP provides the energy required for proteins to force ions in and out of the cell.

Front

What is Osmosis?

Back

The diffusion of water across a selectively permeable membrane.

Front

What is a Hypotonic Solution?

Back

A solution that has a lower concentration of solutes compared to another solution, causing water to move into cells.
