Cell Membrane and Cell Transport

Front

What type of transport moves materials across the cell membrane?

Back

Both Passive and Active Transport.

Front

Which processes move materials in and out of the cell?

Back

Both Passive and Active Transport.

Front

What portion of the phospholipid is hydrophobic and repels water?

Back

Fatty Acid Tails.

Front

What do molecules diffuse until they reach a state of?

Back

Dynamic Equilibrium.

Front

FACILITATED DIFFUSION is an example of _______ transport where molecules move from ____ to ____.

Back

Passive ; High to Low.

Front

Define Passive Transport.

Back

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

Front

Define Active Transport.

Back

The movement of molecules across the cell membrane using energy, usually against a concentration gradient.

Front

What is the role of the cell membrane?

Back

To protect the cell and regulate what enters and exits.

Front

What is a phospholipid?

Back

A molecule that makes up the cell membrane, consisting of a hydrophilic head and hydrophobic tails.

Front

What is dynamic equilibrium?

Back

A state where the concentration of molecules is equal on both sides of the membrane.
