Cell Transport

Front

What regulates what enters and leaves a cell?

Back

Cell Membrane

Front

In passive transport, molecules move from an area of __________ concentration to an area of __________ concentration.

Back

high, low

Front

What is the process called when molecules move across the cell membrane from an area of high concentration to an area of low concentration through a carrier protein?

Back

Facilitated Diffusion

Front

What type of transport moves substances from low to high concentration?

Back

Active Transport

Front

What is the term for the movement of molecules from an area of high concentration to an area of low concentration without the use of energy?

Back

Diffusion

Front

What is the primary function of the cell membrane?

Back

To regulate the movement of substances in and out of the cell.

Front

What is osmosis?

Back

The diffusion of water across a selectively permeable membrane.

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 role do carrier proteins play in facilitated diffusion?

Back

They help transport specific molecules across the cell membrane without using energy.

Front

What is the significance of concentration gradients in cell transport?

Back

Concentration gradients drive the movement of molecules during passive transport.
