Cell Transport

Front

What is dynamic equilibrium in cell transport?

Back

Dynamic equilibrium is the state when material passes into and out of a cell at equal rates, resulting in no net change in concentration between the inside and outside of the cell.

Front

What are the two main types of cell transport?

Back

The two main types of cell transport are Passive Transport and Active Transport.

Front

What is endocytosis?

Back

Endocytosis is a process in which cells surround and engulf substances that are too big to enter the cell.

Front

How do substances move in passive transport?

Back

In passive transport, substances move across the cell membrane with the concentration gradient.

Front

What is an example of simple diffusion?

Back

An example of simple diffusion is the smell of baking cookies spreading throughout the house.

Front

What is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy, following the concentration gradient.

Front

What is active transport?

Back

Active transport is the movement of substances against the concentration gradient, requiring energy (ATP) to occur.

Front

What is osmosis?

Back

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

Front

What is facilitated diffusion?

Back

Facilitated diffusion is a type of passive transport that uses transport proteins to help move substances across the cell membrane.

Front

What role do ion channels play in cell transport?

Back

Ion channels facilitate the movement of ions across the cell membrane, often through facilitated diffusion.
