Passive and Active Transport Flashcard Middle School

Front

What is the structure of the cell membrane?

Back

The cell membrane is composed of a phospholipid bilayer.

Front

Does passive transport stop when equilibrium is reached?

Back

False, passive transport can continue even after equilibrium is reached.

Front

What process removes large particles from the cell?

Back

Exocytosis is the process that removes large particles from the cell.

Front

What type of transport is diffusion?

Back

Diffusion is a type of passive transport.

Front

What is required for active transport to occur?

Back

Active transport requires a transport protein and energy (ATP).

Front

What is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is a type of passive transport that uses transport proteins to help move substances across the membrane.

Front

What is osmosis?

Back

Osmosis is the diffusion of water across a selectively permeable membrane.

Front

What is the difference between active and passive transport?

Back

Active transport requires energy to move substances against their concentration gradient, while passive transport does not.

Front

What role do transport proteins play in cellular transport?

Back

Transport proteins help move substances across the cell membrane, especially during facilitated diffusion and active transport.
