Cell Transport Vocab

Front

What is Exocytosis?

Back

Exocytosis is the process by which a cell forms a vesicle around unwanted particles and expels it out of the cell.

Front

What is Facilitated Diffusion?

Back

Facilitated diffusion is the movement of materials into and out of the cell with the use of proteins but no energy.

What is Passive Transport?

Back

Passive transport is the movement of substances from high concentration to low concentration without the use of energy.

Front

What is Active Transport?

Back

Active transport is the movement of substances from low concentration to high concentration, requiring energy.

Front

Define Pinocytosis.

Back

Pinocytosis is a form of endocytosis where the cell engulfs liquid from the surrounding environment.

Front

Define Endocytosis.

Back

Endocytosis is the process by which cells take in substances by engulfing them in a vesicle.

Front

What is Receptor-mediated Endocytosis?

Back

Receptor-mediated endocytosis is a process where cells absorb metabolites, hormones, other proteins, and in some cases viruses, by the inward budding of the plasma membrane.

What is Osmosis?

Back

Osmosis is the diffusion of water across a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.

What is a Concentration Gradient?

Back

A concentration gradient is the difference in the concentration of a substance across a space.
