Cell Transport

Front

What is endocytosis?

Back

A process by which cells take in substances by engulfing them in a membrane.

Front

What type of transport involves movement from high to low concentration?

Back

Passive Transport

Front

Which transport processes use energy?

Back

Both endocytosis and exocytosis.

Front

What is osmosis?

Back

A form of Passive Transport involving the movement of water across a semipermeable membrane.

Front

What is facilitated diffusion?

Back

The process of moving molecules across a cell membrane via a carrier protein from high to low concentration.

Front

Define active transport.

Back

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

Front

What is passive transport?

Back

The movement of molecules across a cell membrane without the use of energy, following the concentration gradient.

Front

What role do carrier proteins play in cell transport?

Back

They assist in the movement of substances across the cell membrane, especially in facilitated diffusion.

Front

What is exocytosis?

Back

The process by which cells expel materials in vesicles that fuse with the cell membrane.

Front

What is the difference between diffusion and osmosis?

Back

Diffusion is the movement of solutes, while osmosis specifically refers to the movement of water.
