cell transport cell membrane review 2021

Front

What is the state called when both inside and outside of a cell have the same amount of water?

Back

Equilibrium

Front

What is the difference between active and passive transport?

Back

Active transport uses ATP (energy) and passive transport does not need energy.

Front

Does active transport move substances with or against a concentration gradient?

Back

Against a concentration gradient.

Front

What happens to water movement in an isotonic solution?

Back

Water moves equally in and out of the cell.

Front

What is the process called that moves materials into the cell using energy?

Back

Endocytosis.

Front

What is osmosis?

Back

The movement of water across a selectively permeable membrane.

Front

What is diffusion?

Back

The movement of particles from an area of high concentration to an area of low concentration.

Front

What is the role of the cell membrane?

Back

To regulate what enters and leaves the cell.

Front

What is facilitated diffusion?

Back

The process of passive transport of molecules across a cell membrane via specific transmembrane integral proteins.

Front

What is the function of transport proteins?

Back

To help move substances across the cell membrane.
