Cell Transport

Front

What is the definition of Cell Transport?

Back

Movement of material across cell membranes.

Front

What is diffusion?

Back

The process when molecules move from a high concentration to a low concentration.

Front

What is facilitated diffusion?

Back

The process where molecules move across the cell membrane from an area of high concentration to an area of low concentration through a carrier protein.

Front

What is passive transport?

Back

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

Front

What is the energy molecule for all living cells?

Back

ATP (Adenosine Triphosphate).

Front

What role do carrier proteins play in cell transport?

Back

They assist in the movement of molecules across the cell membrane, especially during facilitated diffusion.

Front

What is osmosis?

Back

The diffusion of water molecules across a selectively permeable membrane.

Front

What is the difference between active transport and passive transport?

Back

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

Front

What is a concentration gradient?

Back

A difference in the concentration of a substance across a space.

Front

What is the significance of the cell membrane in cell transport?

Back

It regulates what enters and exits the cell, maintaining homeostasis.
