Cell Transport

Front

What is Passive Transport?

Back

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

Front

What is Active Transport?

Back

Movement of materials against the concentration gradient, requiring energy (ATP) to move substances from low to high concentration.

Front

What is Endocytosis?

Back

A type of active transport where cells engulf materials to bring them into the cell.

Front

What is the concentration gradient?

Back

The difference in concentration of a substance across a space, driving the movement of solutes.

Front

What does it mean for solutes to move with the concentration gradient?

Back

Solutes move from an area of high concentration to an area of low concentration, typically during passive transport.

Front

What is ATP and its role in Active Transport?

Back

Adenosine triphosphate (ATP) is the energy currency of the cell, used to power active transport processes.

Front

What is facilitated diffusion?

Back

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

Front

What is osmosis?

Back

The diffusion of water across a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.

Front

What is exocytosis?

Back

A process of active transport where cells expel materials by vesicles fusing with the cell membrane.

Front

What is the difference between passive and active transport?

Back

Passive transport does not require energy and moves substances down the concentration gradient, while active transport requires energy to move substances against the gradient.
