Cell Transport

Front

What is the process called when particles move from an area of high concentration to an area of low concentration without the use of energy?

Back

Passive transport

Front

Define diffusion in the context of cell transport.

Back

Diffusion is the movement of particles from areas of high concentration to areas of low concentration.

Front

What is equilibrium in terms of cell transport?

Back

Equilibrium is the state when the concentration of particles is equal inside and outside of a cell.

Front

Give an example of osmosis.

Back

A raisin swelling in a cup of water.

Front

What does 'high concentration area' refer to?

Back

An area where particles are tightly packed together.

Front

What is the main difference between passive transport and active transport?

Back

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

Front

What role does the cell membrane play in transport processes?

Back

The cell membrane regulates the movement of substances in and out of the cell.

What is facilitated diffusion?

Back

Facilitated diffusion is the process of passive transport of molecules across the cell membrane via specific transmembrane integral proteins.

Front

How does temperature affect the rate of diffusion?

Back

Higher temperatures increase the kinetic energy of particles, leading to a faster rate of diffusion.

What is osmosis?

Back

Osmosis is the diffusion of water across a selectively permeable membrane.
