EOC Prep: Cell Transport

Front

How does a cell maintain homeostasis?

Back

By regulating what enters and leaves the cell.

Front

What type of cell transport is represented by the process of engulfing materials into the cell?

Back

Endocytosis.

Front

What does it mean for a membrane to be selectively permeable?

Back

It means that some molecules can cross the membrane while others cannot.

Front

What type of transport involves the movement of molecules across a membrane with the help of transport proteins?

Back

Facilitated diffusion.

Front

What is the state called when the concentration of water is equal inside and outside of a cell?

Back

Equilibrium.

Front

What is passive transport?

Back

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

Front

What is active transport?

Back

The movement of molecules against their concentration gradient, requiring energy.

Front

What is osmosis?

Back

The diffusion of water across a selectively permeable membrane.

Front

What is diffusion?

Back

The movement of molecules from an area of higher concentration to an area of lower concentration.

Front

What is the role of the cell membrane?

Back

To act as a protective barrier and regulate the movement of substances in and out of the cell.
