What is the movement of particles from high to low concentration called?

Back

Passive Transport

Front

What type of transport requires the cell to expend energy to pump a solute across a membrane against its gradient?

Back

Active Transport

Front

How does oxygen move from the lungs into the red blood cells?

Back

Diffusion

Front

What cell organelle helps maintain homeostasis by controlling what substances may enter or leave cells?

Back

Cell Membrane

Front

What is the process called when water moves across a selectively permeable membrane?

Back

Osmosis

Front

What is the difference between passive and active transport?

Back

Passive transport does not require energy, while active transport requires energy to move substances against their concentration gradient.

Front

What is facilitated diffusion?

Back

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

Front

What role do transport proteins play in cell transport?

Back

Transport proteins assist in the movement of substances across the cell membrane, either passively or actively.

Front

What is the significance of the concentration gradient in cell transport?

Back

The concentration gradient drives the movement of substances; particles move from areas of higher concentration to areas of lower concentration.
