Cell Transport

Front

What is a Channel Protein?

Back

A type of protein that allows specific molecules to pass through the cell membrane, facilitating transport across the membrane.

Front

What does Semi-Permeable mean?

Back

A property of a membrane that allows certain substances to pass through while blocking others.

Front

What is Phagocytosis?

Back

A type of active transport where a cell engulfs large particles or solids, forming a vesicle.

Front

What is Endocytosis?

Back

A process by which cells take in substances by engulfing them in a vesicle; it is not a form of passive transport.

Front

What is a Hypertonic solution?

Back

A solution that has a higher concentration of solutes compared to another solution, causing cells to lose water.

Front

What is Osmosis?

Back

The movement of water molecules through a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is Diffusion?

Back

The process by which molecules spread from areas of high concentration to areas of low concentration.

Front

What is Facilitated Diffusion?

Back

A type of passive transport that uses channel or carrier proteins to help move substances across the cell membrane.

Front

What is an Isotonic solution?

Back

A solution that has the same concentration of solutes as another solution, resulting in no net movement of water.

Front

What is Active Transport?

Back

The movement of substances across a cell membrane against their concentration gradient, requiring energy.
