Cell Transport

Front

What is equilibrium in the context of cell transport?

Back

Equilibrium refers to the concentration of molecules on one side of the membrane being equal to the other side of the membrane.

Front

What type of transport requires energy to move molecules against the concentration gradient?

Back

Active transport.

Front

What happens to a cell in a hypertonic solution?

Back

The cell loses water and shrinks.

Front

What is homeostasis?

Back

Balance, or maintaining relatively stable conditions.

Front

What does semi-permeable mean?

Back

To allow only some materials across the membrane.

Front

What is passive transport?

Back

The movement of molecules across a cell membrane without the use of energy.

Front

What is facilitated diffusion?

Back

A process that allows molecules to cross membranes with the assistance of special proteins.

Front

What is osmosis?

Back

The diffusion of water across a selectively permeable membrane.

Front

What is a hypotonic solution?

Back

A solution with a lower concentration of solutes compared to another solution.

Front

What is a hypertonic solution?

Back

A solution with a higher concentration of solutes compared to another solution.
