Cell Transport

Front

What is Exocytosis?

Back

Exocytosis is the process by which large molecules exit a cell by being packaged in vesicles that fuse with the cell membrane.

Front

What molecule powers Active Transport?

Back

ATP (Adenosine Triphosphate) is the molecule that provides energy for Active Transport.

Front

What is Endocytosis?

Back

Endocytosis is the process by which a cell takes in large molecules by engulfing them with the cell membrane.

Front

What is the direction of molecule movement during diffusion?

Back

Molecules move from high concentration to low concentration during diffusion.

Front

What is the role of the Cell Membrane?

Back

The Cell Membrane is responsible for maintaining homeostasis by regulating what enters and exits the cell.

Front

Define Facilitated Diffusion.

Back

Facilitated diffusion is the process of passive transport of molecules across a cell membrane via specific transmembrane proteins.

Front

What is Phagocytosis?

Back

Phagocytosis is a type of endocytosis where a cell engulfs large particles or cells.

Front

What is Pinocytosis?

Back

Pinocytosis is a type of endocytosis where a cell takes in liquid from the surrounding environment.

Front

What is the difference between Active Transport and Passive Transport?

Back

Active Transport requires energy (ATP) to move substances against their concentration gradient, while Passive Transport does not require energy and moves substances along their concentration gradient.

Front

What is Osmosis?

Back

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