Cell Transport

Front

What is Exocytosis?

Back

A process where cells expel materials using vesicles, requiring energy (Active Transport).

Front

What type of transport occurs from low to high concentration?

Back

Active Transport.

Front

What is Passive Transport?

Back

Movement of materials from high to low concentration without energy, often through protein channels.

Front

What is the role of ATP in cell transport?

Back

ATP provides energy for Active Transport processes.

Front

What is Endocytosis?

Back

A process that takes substances into a cell, requiring energy (Active Transport).

Front

What is the difference between Active Transport and Passive Transport?

Back

Active Transport requires energy to move substances against their concentration gradient, while Passive Transport does not.

Front

What is a concentration gradient?

Back

A difference in the concentration of a substance across a space, driving the movement of substances.

Front

What is facilitated diffusion?

Back

A type of Passive Transport that uses protein channels to help move substances across the cell membrane.

Front

What is osmosis?

Back

The diffusion of water across a selectively permeable membrane, a type of Passive Transport.

Front

What is the function of protein channels in cell transport?

Back

They facilitate the movement of specific molecules across the cell membrane, especially in Passive Transport.
