Cell Transport

Front

What is Passive Transport?

Back

Movement of materials from high to low concentration through a protein channel without using energy.

Front

What is Active Transport?

Back

Movement of materials against the concentration gradient, requiring energy.

Front

What is Endocytosis?

Back

The process of taking substances into a cell by engulfing them.

Front

What is Exocytosis?

Back

The process of expelling substances from a cell by vesicles fusing with the cell membrane.

Front

What is the concentration gradient?

Back

The difference in concentration of a substance across a space.

Front

What is the role of protein channels in cell transport?

Back

They facilitate the movement of specific molecules across the cell membrane.

Front

What is the difference between passive and active transport?

Back

Passive transport does not require energy, while active transport does.

Front

What are solutes?

Back

Substances dissolved in a solvent, such as salt in water.

Front

What is osmosis?

Back

The diffusion of water across a selectively permeable membrane.

Front

What is facilitated diffusion?

Back

A type of passive transport that uses protein channels to help move molecules.
