Cell Transport

Front

What is ATP?

Back

ATP (Adenosine Triphosphate) is a molecule that carries energy within cells, used in active transport.

Front

What is Active Transport?

Back

Active transport is the movement of substances across a cell membrane against their concentration gradient, requiring energy (ATP).

Front

What is Passive Transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy, following the concentration gradient.

Front

What is Endocytosis?

Back

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

Front

What is Exocytosis?

Back

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

Front

What is Facilitated Diffusion?

Back

Facilitated diffusion is the process of transporting substances across a cell membrane with the help of carrier proteins, without using energy.

Front

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.

Front

What is a Cell Membrane?

Back

The cell membrane is a biological membrane that separates and protects the interior of all cells from the outside environment.

Front

What is Homeostasis?

Back

Homeostasis is the process by which living organisms regulate their internal environment to maintain stable, constant conditions.

Front

What is a Hypertonic Solution?

Back

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