Cell Transport

Front

What is Passive Transport?

Back

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

Front

What is Active Transport?

Back

Movement of particles from low to high concentration that requires energy.

Front

What does it mean to move against the concentration gradient?

Back

It refers to moving particles from an area of lower concentration to an area of higher concentration, which requires energy.

Front

What is endocytosis?

Back

A process where cells engulf substances from outside the cell membrane, requiring energy.

Front

What is exocytosis?

Back

A process where cells expel substances to the outside of the cell, requiring energy.

Front

What is ATP?

Back

Adenosine triphosphate, a molecule that carries energy within cells.

Front

What is the concentration gradient?

Back

The difference in concentration of a substance between two areas.

Front

What is osmosis?

Back

The movement of water across a semipermeable membrane from an area of low solute concentration to an area of high solute concentration.

Front

What role do transport proteins play in cell transport?

Back

They assist in the movement of substances across the cell membrane, especially for larger or polar molecules.

Front

What is facilitated diffusion?

Back

A type of passive transport that uses transport proteins to move molecules across the membrane without energy.
