Cell Transport FLASHCARD

Front

What type of solution would cause a cell to swell?

Back

Hypotonic solution causes a cell to swell because it has a lower concentration of solutes compared to the inside of the cell, leading to water entering the cell.

Front

What is Passive Transport?

Back

Passive Transport is the movement of particles across a cell membrane from an area of high concentration to an area of low concentration without the use of energy.

Front

What is Active Transport?

Back

Active Transport is the movement of particles against a concentration gradient, from an area of low concentration to an area of high concentration, requiring energy.

Front

What is Osmosis?

Back

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

Front

What is Endocytosis?

Back

Endocytosis is a form of Active Transport where cells engulf substances from the outside environment, bringing them into the cell.

Front

What is Diffusion?

Back

Diffusion is the process by which molecules spread from areas of high concentration to areas of low concentration until equilibrium is reached.

Front

What happens during Active Transport?

Back

During Active Transport, cells use energy (ATP) to move substances against their concentration gradient, often involving transport proteins.

Front

What is a Hypertonic solution?

Back

A Hypertonic solution has a higher concentration of solutes compared to the inside of the cell, causing the cell to lose water and shrink.

Front

What is an Isotonic solution?

Back

An Isotonic solution has an equal concentration of solutes inside and outside the cell, resulting in no net movement of water.

Front

What role do channel proteins play in Passive Transport?

Back

Channel proteins facilitate the movement of specific molecules across the cell membrane during Passive Transport, allowing substances to pass through more easily.
