FLASHCARD QUESTION

Front

What is Passive Transport?

Back

Passive transport is the movement of molecules across a cell membrane without the use of energy, typically from an area of high concentration to an area of low concentration.

2.

FLASHCARD QUESTION

Front

What is Active Transport?

Back

Active transport is the movement of molecules across a cell membrane using energy, typically from an area of low concentration to an area of high concentration.

3.

FLASHCARD QUESTION

Front

What is Diffusion?

Back

Diffusion is the process by which molecules spread from areas of high concentration to areas of low concentration until they are evenly distributed.

4.

FLASHCARD QUESTION

Front

What is Facilitated Diffusion?

Back

Facilitated diffusion is a type of passive transport that uses protein channels to help move molecules across the cell membrane from high to low concentration.

5.

FLASHCARD QUESTION

Front

What is Osmosis?

Back

Osmosis is the diffusion of water molecules through a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.

6.

FLASHCARD QUESTION

Front

What role do protein channels play in cell transport?

Back

Protein channels facilitate the movement of specific molecules across the cell membrane, allowing for selective transport.

7.

FLASHCARD QUESTION

Front

What is the main function of the cell membrane?

Back

The cell membrane regulates what enters and exits the cell, providing protection and support.
