Cell Transport

Front

What is Passive Transport?

Back

Movement of materials from high to low concentration without the use of energy.

Front

What is Active Transport?

Back

Movement of materials from low to high concentration using energy (ATP).

Front

What is Osmosis?

Back

The diffusion of water across a selectively permeable membrane.

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.

Front

What role do protein channels play in cell transport?

Back

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

Front

What is the difference between diffusion and osmosis?

Back

Diffusion is the movement of solutes, while osmosis is the movement of water.

Front

What is a selectively permeable membrane?

Back

A membrane that allows certain substances to pass while blocking others.

Front

What is the significance of ATP in Active Transport?

Back

ATP provides the energy required to move substances against their concentration gradient.

Front

What is facilitated diffusion?

Back

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