Passive Transport

Front

What is Selective Permeability?

Back

The ability of the cell membrane to allow some things to pass through while preventing other things from passing through.

Front

What is osmosis?

Back

The movement of water to an area of low to high concentration of solutes.

Front

What does Equilibrium mean in the context of cell membranes?

Back

Equal amount of substance on either side of the membrane.

Front

What does Passive Transport mean?

Back

No energy is used.

Front

What is the primary substance involved in osmosis?

Back

Water.

Front

What are the two main types of transport across cell membranes?

Back

Passive transport and active transport.

Front

What is the difference between passive transport and active transport?

Back

Passive transport does not require energy, while active transport requires energy to move substances against their concentration gradient.

Front

What is diffusion?

Back

The movement of molecules from an area of high concentration to an area of low concentration.

Front

What role do protein channels play in passive transport?

Back

They facilitate the movement of specific molecules across the cell membrane without using energy.

Front

What is facilitated diffusion?

Back

A type of passive transport that uses protein channels to help move substances across the membrane.
